I'm having a similar problem with BT/OpenReach. In my case I have two ISPs involved, PlusNet and AAISP.
I've got two FTTC lines, both with a common network fault. OR have known since 17th March that they need to dig up a section of the 30 pair cable and replace it. It took about a month for this detail to make it as far as BT, despite me talking to endless OR engineers about it and them talking to their managers to confirm what needs doing.
BT kept sending new OR engineers even when they should have not there was nothing they could do until the common fault was fixed. Most days they send two out, one for each line, sometimes two at a time...
I estimate I've had well over 2 dozen engineer visits or attempted visits (they appeared to stopped bothering to book appointments after a while). In
none of the visits did the engineers know the state of play before they turned up.
They have at least stopped doing that, but I've now been waiting for weeks as the keep giving dates to fix the fault that pass without any work happening. The latest date is the 19th June, at which point the faults will have been open over two months.
So despite having two ISPs badgering BT, getting OR to actually do anything to fix non trivial faults seems to be a problem.
