I haven't posted in a while, didn't want to seem like I was ignoring the thread, had already decided what to to but the more I read the more I'm considering just telling him I'd rather not share or just give him access while I'm at work.
It is expensive and according to BT I'm on a very special rate, this thread spurred me on to ring BT and try to get my installation charge wavered but they say because I'm on a reduced rate they can't do it, I told them that even at the reduced rate I'm still paying more than their competitors for the same or better package, God knows how BT manage to charge so much and get away with it, I suppose it's because it's a household name.
Anyway I rang sky and they can give me truly unlimited internet and phone line rental for £22.50 a month and they are LLU enabled on my local exchange, plus, only £19 for installation, the only downside is though that I'll have to wait another month for an engineer but I'm thinking of leaving BT and going with sky now, plus it's only £57 to brake out of my BT contract.
