Here’s what consumers have asked with answers from Onecom staff and previous consumers.
There is no mention of the 3 year contract when the salesman cold calls you.
France's all they do is call your current supplier and pretend to be you and try to get the fee waiverd if this dosnt work there's nothing in the contract that holds them liable and you have already agreed to a contract with them they have no concerned over continue custom they will sting you once and make there money
If you can't through on the phone send them an email - what they do with it is their problem but it will be proof you cancelled in time. And if later than the cooling off period, you were mis-sold anywayso have a right to cancel. Then cancel the DD and go back to your old supplier. Good luck
They are very carefull with the way they word things for instance "we will endevor to waiver your ETF" so what there saying is they will try, And this was done by there legal team (consists of 2 people with no legal experance calling BT and pretending to be the customer saying because BT have up there prices your legally allowed to leave the contract free of charge, with BT just saying the charge is valid, and now they dont have a legal team atm so there not to concerned about customer happyness its a fly by company
Ignore them. You cancelled the contract because it was mis-sold. You have cancelled the DD, just make sure it is not re-instated by them. Given the reviews I have just read I doubt they will take it down the legal route. You can always try threatening to sue for harrassment but, personally, I would just ignore them. Don't delete emails though - they are evidence should you need it.
