I am yes, i found out the normal telephone based support to be attrocious but a simple PM to a BT rep on here got me a phone call from him and an engineer booked for the next day.
I also found out they do a brilliant contact service via Twitter too 
Telephone support with most
large ISPs seems to be limited to telling people how to get to set up their email account and such-like. In other words, basic customer training.
It isn't for problem resolution where something is not working to spec.
Given the volume they must have to deal with that is understandable. But the failure to have a rapid and almost automatic escalation to a fault resolution team is ridiculous and counter-productive, as well as being bad for the morale of the staff concerned.
Why oh why, with so many such ISPs, does it need to be public complaints in various forums, not just these ones, about possibly weeks or months of problems and customer frustration before BT_Care or their equivalent elsewhere step in and it is sorted within hours?
These people do an excellent job, but how come their own telephone support level can't pass stuff to them?
