Scam artists
February 26, 2025

Beware, these are a very shady outfit. Total BS on the phone, lies after lies. Just steer clear! You've been warned.
Apparently halved my mobile and BB costs. Total BS,, my bill would be 5x higher! Saw the scam early and think I have escaped their clutches 🤞🤞

OneCom have the worst customer service I have ever experienced. I have been a business customer with them for a few years. I changed networks, service provided by onecom. My phone lines were deactivated and I was left without my business numbers for 3 weeks. They have an overseas call centre that take 30 plus minutes to answer. They only operate during the working day. You have to explain the whole situation every time you speak to someone, nobody takes responsibility for your account. Onecom offered me £50.00 for the inconvenience, I declined as I wanted my numbers working instead. The call taker didn't know what to do, so she ended the call and emailed me the offer, however no offer to resolve my problem. Changing networks is a simple task, onecom has made this a 3 week huge interruption to business. I had to purchase PAYG sim cards, my phone line was deactivated whilst I was out of town at a conference. I had no way of getting in touch with my team, equipment on the lorry needs data so that my crews can access the jobs, this was also deactivated during the day without any warning. The CCTV is monitored remotely, this is also via a data sim, the CCTV was impacted. So many elements of my business have been interrupted by me choosing to remain a oncome customer. Please take my advice, do not use them. If you are currently with them, move away at the end of the contract, as when it goes wrong, they do not care and will not resolve the problems. This will cost you business.

Preying on the elderly
January 2, 2024

OneCom are taking my elderly dementia ridden Dad to court to pay £1000 fine for cancelling his contract a few years ago because the broadband hardly ever worked. OneCom customer service was non existent and no one would fix the problems so he had no alternative but to switch providers. Shame on you OneCom preying on the vulnerable with your dodgy contracts and shoddy service. See you in court!

I would like to give no stars but that isn't an option.

Please, please do not join Onecom! Don't believe these reviews. They do not care about you, they are rude, aggressive, unhelpful, they lie. You'll be stuck between them and the network provider when you need help as each party says it's down to the other.

The stress they have caused me since joining them in May 2023 is unbelievable. No one responds to you, you are constantly chasing them for answers. Which usually comes across as them sitting on their high horse, not caring, knowing there right and can't be wrong.

I'm sure they've breached some kind of data protection law, as every time I ring complaints (which is a lot) everyone knows my name before I even tell them?

They have breached terms in my contract and they won't terminate the contract unless I pay the exit fee!

Please, please do not make the same mistake as I did!

I was promised deal after deal to join onecome. My final contract was agreed and signed at £36 per month. I am now 4 months into my contract and I haven't seen one bill at the agreed price. As well as the £36 deal I was gifted two free perks and a WiFi dongle to entice me over from another company. These items in fact were not free. I paid the FULL amount of these items in month one leaving me a bill of £150 plus. Then in months 3 and 4 paid more than double my agreed contract amount (this eill also continue untill my contract ends)

When I contacted ONECOM I was met with no help in the matter what so ever and told to look at the 'terms and conditions' and that there is nothing they will do.

I now have seen countless other reviews with the same issue knowing this company to be a scam.

Please AVOID AT ALL COSTS!

Don't trust to any words they say. They promise to reduce my monthly costs and offer some additional "free" services. They verbally assured me that I will pay a certain amount and then they sent a sneaky contract. After a year with them ended up Paying £260 monthly instead of verbally agreed £48!

Terrible con company
April 10, 2023

Before considering taking a contract out with this company, do the following:

- Be aware this is a business-to-business contract. It is not a business-to-consumer contract. So there is NO cooling off period. They also have much less obligation to tell you about all their sneaky tactics.

- They will promise you a very low amount of £7.00 per month or so for a phone

- When they give you the contract it will say £7.00 per month for 17 months and then £55.00 per month until moth 36

- They will say you will benefit from "further reductions" at month 17. This does not mean your bill will be less than £7.00. It means it will be less than £55.00 (so it could be £54.00!)

- Understand that you will be charged the full amount of the contract each month (i.e. £55.00 in the example above). Onecom will then issue a refund of £48.00 to balance it out. However, they also add VAT, so they will charge you £55.00+VAT = £66.00. But they will not refund any VAT. So you will pay £66-£48 = £18.00 instead of the £7.00 they originally promised.

- Make sure anything they promise you about the tariff is in writing. Because they promise you all sorts of things that aren't in the final contract.

- Make sure that, when they go through the contract with you at the point of signing, that EVERYTHING you have been promised is included in the tariff. I have emails where they promised all sorts of things. But because they didn't confirm it at the final point of signing, they say it's not included.

- The inflation increase each year will be on the FULL price of the contract (i.e. £55.00 + the increase). Not just on the discounted amount.

- Do not let them pressure you into signing the deal the same day. The deal will not expire

- If they promise you free wi-fi (mifi) devices, it's not true. They are 'free' for a period and then they will charge you through the nose for them. They also don't work very well. Just use hotspot on your phone if you must.

These are all the tricks I can think of at present. Just look out for them if you feel tempted to sign up with them as the reality is very different to the promise!

They are purposefully misleading and deceitful in their selling practices hitting people with extortionate bills. I thought it would be £30 a month for a mobile phone contract but was hit with my first bill for over £300. They target vulnerable self employed people with business contracts that have no cooling off period and naïve individuals are not aware of this and are locked in for 36 months. They deny any wrongdoing and continue to say that everything is confirmed at the point of sale which is further lies. I've had to get the Ofcom regulator CISAS involved to cancel the contract as they sided with me that I was mis-sold. Onecom continue to deny that I was mis-sold and offer no apologies, it has caused me so much stress and hassle and I detect no remorse from their staff as they already know what they are doing is wrong and they continue to do it.

March 10, 2023

Long story but I signed up March 2021. Seems like a good deal but 17 months into the contract costs went up dramatically. I've no phone signal worth talking about where I work from home. Complained - they can't fix that and the only way they will reduce the cost is if you sign up for a further 36 months. I refuse because I just want out. They don't do complaints and as it's a business contract Complaints Ombudsman doesn't apply. Avoid Avoid Avoide

Please be careful!
January 23, 2023

This company are so polite and friendly to distract you from their devious miss selling! They sound very professional but it's what you don't hear that matters! They give you a great price for a 36 month contract without telling you that they great price is only for the first 17 months, by then you have to agree to whatever price they give you as you are contracted to them for another 18 months! They add more services to your contract without discussing it with you and then rush you through the signing process so you don't notice. Once you've signed you find out 'THERE IS NO COOLING OFF PERIOD!' There is even a Facebook page full of people who have had this happen to them. Please, please be careful!

A very devious, corrupt company who take joy in miss-selling customers. Be very careful checking your contract with OneCom, I verbally signed up to an £18 a month contract (cheaper than my previous deal). After a month my first bill arrived at nearly £200! I called to cancel and was quoted a fee of about £5000+ to get out of my contract as there was no cooling off period. After 2 months the telecoms governing body CISAS instructed OneCom to cancel my contract, refund me and send me a letter of apology. Google the words OneCom and SCAM or FRAUD and get a true picture of this company. My advice would be run for the hills and don't even entertain a conversation with them or it'll cost you x10 what you're expecting.

DO NOT USE!
September 9, 2022

If you are self employed/sole trader and are not VAT registered do not use! Their sales people quote EX VAT and there is no cooling off period so once you sign that contract thats it. Plus all the discounts that they hard sell you over the phone end in 17 months (they don't mention that). If you don't thoroughly read the contract you do not notice this as there is so much on it while a sales person is rushing you to sign.

Warning to all - Avoid 'OneCom' at all costs.

I got a very long cold call from OneCom. They talked me into changing networks and to a business tariff on my mobile (I didn't know B2B consumer laws do not offer the same rights as a private buyer) Follow this link for more info on B2B contracts:-
https://reducer.co.uk/blog/understanding-business-to-business-contracts

I did sign up for the mobile tariff they offered me after over 30 mins of hard sell but changed my mind 3 days later and tried to cancel (within the 14 day cool off period!) I have been told there is no 14 day cooling off period for business customers! So I am pretty much stuck with this bad contract for at least 2 years if not longer.

The Deal: OneCom offer you an expensive phone tariff (i. E. £44.81/per month/ sim only) then give you a monthly discount of £35 making the total plan £9.81 (sounds good!). This was the price I was quoted (I missed they said it was ex VAT!). Ex VAT – Not Plus VAT which is more understandable terminology!

What they don't tell you is you pay VAT on the full amount (£44.81 + VAT = £53.77) not the quoted plan cost of £9.81. So my actual monthly cost will be £18.77 (+ £8.96 VAT on the £44.81). This is never made clear, double the amount I was quoted.

The contract is with OneCom for 3 years (they told me 2 years over the phone!) with a tariff review at 18 months. The discount is only for 17 months. So if you don't call for the tariff review the price bounces up to the full expensive price for the remaining 18 months of the contract. If you DO call them for a tariff review you can negotiate a new tariff BUT essentially you may be signing up to another 2 years!

Please:-
Do not use this company
Do your homework before signing up to a new contract (especially business customers)
Always look at the One Star reviews on review sites.

OneCom have lots of disturbing one star reviews on Trust Pilot https://uk.trustpilot.com/review/www.onecom.co.uk?stars=1

I can't tell you how very stupid and annoyed I feel with myself right now.

I have now recieved a deadlock letter from OneCom to take this matter to Ofcom/ CISAS. One Com use CISAS instead of Ofcom you can call them on *******2814 to lodge you complaint.

Contracts and agreements appear to consistently change from one day to the next as they pile you with paper work! Getting everything in writing doesn't stop them from consistently amending the contract to suit them profit-wise. You are better off getting a contract directly from your phone provider. They will stop at nothing to get as much money as they can off you - their profit is their main focus not you the customer. Their starting point is a promise of a cheaper and better deal but that is just to get you hooked into their game. The deal is adjusted over and over to suit them. If you decide to take a contract with OneCom, make sure you make good use of your 14 day cancellation period; check and cross-check all the pile of paper work that comes your way from them to make sure it is all saying the same thing!

Got hooked into a 36month Business Contract and given bad advice about terminating my existing contract early. No way to terminate early or cancel like a personal contract. Cost me. Thousands of £. Will never use them again or recommend them.
