On the weekend of the 9-10 of September I was in Belgium, putting my trust in your "roam like home" (EU) experience covered within my contract.
Last time I checked Belgium is still in the EU but despite commiting to provide my with the ability to use my data package anywhere in the EU, you left me stranded with no data all of that weekend, resorting to public wifi or buying a separate sim card.
None of your representative was able to help, some completely clueless and unprofessional and others just gave me no solution, except for opening a ticket to some tech team to look at within 9-15 days.
A complete joke considering I was in Europe for 24 hrs.
I travel frequently on short trips for work, and it's clear that your services are completely unreliable on all fronts, so as soon as I returned home I requested my PAC code via sms.
The sms informed me that I need to pay £337 to leave you.
You are in clear breach of your contract with me by not providing the services you committed to so there is absolutely no way I'm paying this money to leave you.
Seeing this I called to make my complaint known and looking to cancel this breached commitment money, but no regular support team member can help me, only a manager.
I've requested a manager call back on the 12th of September and was told that would take 24 hrs.
Those have passed, I call again, 24 hrs more, those pass I call again, and this time I was told that the manager that was supposed to call me was unavailable to make the call, so no call was made.
Rep wad really sorry and even promised a manager will call me today and that by end of her shift (8pm, 14th of Sep) she will call me to check in if someone hd called.
Not the manager nor the rep called back.
Tomorrow - now 72 hrs after I've requested a manager call, I will call again, and I'll either not get off the line until I get a manager, or I will call cs consistently throughout this day and every single day that follows until you release me from this horrible commitment that you as a company breached.
The terrible service definitely pushes me even further away.
Worst mobile company I've ever dealt with in my life.
If you don't release me from my contract with no expense I will be suing you. I've already started sharing this all over the review site.
You should be ashamed of yourself.

Thought I would update on my situation and how bad O2 is, I switched to the 13 pro max 1tb as only one they had in store and put deposit down for the 14 pro max 256gb which collected 11th of November so got deposit back and handed back the 13, it's now 16th March and still left with paying for the 13 not the 14 as found out in the end the las cancelled the wrong contract not only that but she put the returning device as the 14 pro max 128gb when I got the 256gb for starters but it should of been the 13, the store isn't interested and won't take responsibility and either will customer service as been to the store 7x as customer service tell me I have to do it in store, and been on the phone 8x or so as the store tell me they can't do nowt that I have to phone customer service, got trading standards involved as o2 have breached the contract,

Kept being told lies and promises told I would get a call back twice and I didn't, told I would get a call back from a manager I didn't, told I would get a call back today I didn't, told I would get my money back 10 days after the 15th February never did, waiting on money still, told I would get the phone first as started nee contract and then send this back but not received phone yet told need to send this one back first, so all in all switch up is a waste of time and o2 as a whole is a scam.
