I think NTL still owe me money

Will have to chase them up sometime soon really. Trouble is, they don't send bills through the post, one of mates has told me that bills are on the ntl website and they should have gave me a password and stuff for it, but alas! They havn't even told me about the internet billing service. When i do get around to ringing them, I think were going to having some pretty stern words.
