Yeah, I know. It's only BT directly with whom I have a gripe - any dealing with them has, over the last 30 years, been somewhere between unsatisfactory and a shambles. I've learned my lesson.
Dealing with the weasel's tentacles, though, doesn't seem to be doomed (yet). Cellnet - tolerable. OpenReach - tolerable. EE, tolerable. Wish me luck.
