Excellent service and very prompt all done on the chat on line. This service works I believe is quicker than filling in a form that easily make mistakes. Having someone to communicate with that is prompt and efficient makes all the difference.
I would highly recommend the chat service it much quicker than phone

Wanted to upgrade my phone and onecom matched a competitors deal exactly if not better as I got to keep The entertainment package for 2 more years! Karl Davies has dealt with my past 2 upgrades over 4 years and he's always highly professional, makes it easy for me to understand and always finds a way to make the process a little more fun/banter! Top Lad!

Answer: There is no mention of the 3 year contract when the salesman cold calls you.
Answer: 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.
Answer: 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
Answer: 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
