I had the misfortune to deal with one of those.
A friends broadband packed up on thursday.
They were a nightmare. They couldn't deal with the fact he had a router. They seemed to think a router was just for wireless, not for the security benefits.
They even thought the operating system would make a difference (we could see the router admin page and it said there was no PPP connection).
One operative even inteneded to log that we had refused to help with diagnosis, despite the fact that I had explained to him that the point that the system was failing was the PPP connection (Not just the password/username), and we had confirmed the router worked and reflashed it to the latest firmware, just in case. My friend lost his temper with him at that point and had a really good go at him, (I'd already been pushed to the point of raising my voice earlier, which takes a lot.)
They tried to imply the router was at fault or incompatible, depite the fact that it was a decent make (Draytek), I had taken it to my house where it worked perfectly on talktalk, and that it had been working for months before.
My friend created such a fuss with Customer services the next day that they gave him a goodwill gesture of £30 (which we drank on friday night :) :) )
The service reappeared at the end of the weekend.
He gets about 2.5M connection, where his router gave 7.5M on my talktalk line just round the corner.
I assume many Pipex customers are making their escape plans.
