I got a new BT line and decided to change my package within the 7 cooling off period. When I got my bill I had been charged £170 cancellation charges. Called India and they said they would be refunded and got a reference no. Have done this 3 times now and the amount is still there and my direct debit goes out this friday. Any ideas?!

Send a pained but polite complaint to ben.verwaayen@bt.com laying out all the facts, that you cancelled within the 'days of grace' but were still charged.
Hopefully, HLC can sort it.
PS. Get straight round to the bank and cancel the DD.
