I'm still not sure Openreach have a record of where my line is jumpered in the PCP after the LAST time they disconnected me and hooked my E side up to some Talk Talk customer.
The Talk Talk customer got reconnected in a day or two as a line fault, my pair was left floating in the wind for a week because it was raised as a broadband fault.
It only got fixed because eventually the engineer turned up to my house (as he had been given zero information) so I FINALLY had a chance to explain what the fault was, rather than them using pure guesswork and getting it wrong.
I do feel sorry for Openreach engineers, it seems they are expected to perform miracles with zero information sometimes. Its particularly frustrating when both me and my ISP knew more than the engineer did about the situation, because Openreach didn't pass anything on.
As I was on Origin at the time in the early days of the ISP, I literally had the CEO camped at my PCP at one point trying to catch an engineer to explain the situation, but they never turned up on time.
In their defence, I think I was still on Digital Region and it seemed Openreach was ill prepared for that kind of LLU setup so EVERYONE was confused. But it always comes down to poor record keeping it seems.
