I was utterly disgusted wth NTL too, cancelling Cable Broadband, telephone and digital television. Like you, I received a bill a month after cacellation, and they can go to hell. I'm not paying any more money to them, and have cancelled my direct debits to NTL. The spread of 0870 numbers is getting out of hand, even Dell now require you to call an 0870 number to buy a computer. I've just given up altogether on anyone using 0870 numbers. Also, 0845 numbers are almost as bad - the whole thing is a scam, with charges between 5p and £1.50. I've asked OFCOM to cancel 0845/0870/09... numbers, but they won't play.

I always call the sales line on 0800 052 0855. Option 2 then puts you through to customer services. You have to wait while a recording tells you that "in future" you can call an 0845 number to go direct to customer services. But then you are put through.
