Thank you for those links. Will give them a whirl. There is no doubt about the line 'ownership'; we have the notification letters from TT telling us that broadband is now active and giving the username and password. Unfortunately, they didn't inform themselves

PPruNe Pop - How did you mange to make contact with anyone? I have, once, but the person on the other end was almost unintelligible and, when I eventually managed to translate what she was saying, she knew NOTHING of any use.
Duckbutt - that transfer to BT sounds like very bad news.... Waitrose were (last week) classed as the best UK broadband provider, by 'Which?' magazine. I would suspect that BT were very little better than TalkTalk
