I was on NTL's £15 per month phone/dialup package, before I moved to ADSL last year. However, it was troublesome cancelling, having both phoned a few times, as well as sending a letter by recorded delivery, yet they still claimed a month later that they had no record of my cancellation request, and the service was still active. After a few more calls, a customer representative appeared to give in, and cancelled the service there and then - and said that was the end of it, nothing to pay, etc.
However, today I recieved a phone call from NTL, saying I owe them £15 from an unpaid direct debit - which I'm guessing would be from around the time that we should have been disconnected, but weren't.
Any advice would be much appreciated
