We have been waiting six months for something.
Admittedly it has turned into a bigger job for them than they were expecting[includes closing a minor road for 1/2 a day], but we used to be given dates that were moved forward a month, then two weeks, then they didnt have poles in the warehouse, then they needed authorisation from someone[possibly the council, we couldnt quite work out from where, but that was our best guess]. And still the saga goes on.
I think there has been a thread about them before. I may go and look sometime.
Previously, ourselves and other neighbours have tried to use a different company for something or other, but parts of it still had to be done by BT, so we all decided to stay with them.
I could go on and on about the company, but I had better not!
