NTL aren't all bad.
About 2 years ago while a student living in a shared house we ordered cable internet off NTL. The Modem came eventually but after about 6 weeks there was still no access to the net, we told them to forget about it. After this the internet was turned on and we were not charged for it. I lived in this house up to about 3 months ago with free cable modem and internet access and as far as i know the house still has it.
A horaaah for incompatance!
