AA charge a hefty premium for this 'support'?
I would be seriously worried if I were paying way over the odds for this, at best, unprofessional behaviour.
It's no wonder AAISP consistently get the lowest support ratings and highest overall ratings year after year after year, and are well known everywhere but in your household for being able to get Openreach to act when no other ISP can. (Not).
I really can't understand how they stay in business. Or why you didn't set up as an ISP years ago and have trounced the market. (Actually I have no difficulty whatsoever in understanding both of those).
How many years has the OP had this fault?
How many times has it been diagnosed and repair jobs raised?
How many ISPs using pussy-footing "yes sir, no sir" handling of Openreach have failed to have it corrected?
Have you accessed the conventionally worded complaints AA have earlier sent to Openreach over the last four or five months
, which have in the past resulted in yet again a valid diagnosis, job to rectify booked, then cancelled for no good reason?
How many of the OP's neighbours also have duff connections?
Which ISP do you suggest to the OP will finally get this resolved? Or is making helpful suggestion completely alien to your way of thinking?
Have you a way to get the fault fixed? You could make a lot of money if you could do better than AA at getting Openreach to handle problems.
Do they pay you to disparage users and ISP methods?
