Which just shows you are determined to plough on in apparently complete ignorance of the easily available history of this problem since it was first posted about literally years ago. You seem to have a closed mind approach resulting from a couple of posts containing justified remarks by AA, whatever your personal opinion of that language and how the matter should be handled by them.
Oddly, it looks as though there is a slight possibility that Openreach are actually going to deal appropriately with the fault, which is something at least two other ISOs have failed to achieve. Though I am not convinced a dig is going to happen, and I expect the OP has the same doubt.
That rather makes it look as though what you have seen posted is the only language Openreach understand.
As you claim to know these steps and procedures, it might help if you listed them, so the OP can tell you which he is aware of having been followed by any one of the at least four ISPs he has been with while it continued. You would, amazingly, possibly help the OP in asking his ISP if certain ones of them have been tried. Instead of putting yourself forward as a supreme judge of how to get things sorted. With no facts other than what has been copied into this thread to go on.
It is also abundantly clear that individual engineers are not being "shot down". They can only report back on whatever they have been tasked to do, however inappropriate those instructions are. I am quite sure the OP is not criticising them personally.
As for some of the detail of your post:-
1) It is patently clear this is not a fibre fault, so your suggested route there is fatuous.
2) You seem to suggest that the best ISP known about on these forums is ignorant of official channels. But being a relative minnow, as I pointed out previously, they are restricted to the actions specified in their contracts with BT Wholesale and Openreach. Those parts of BT Group have clearly allowed the line problem to persist for years, despite being known to have multiple instances of diagnostic evidence of it. Can you explain how multiple disconnections per day at times are not service affecting?
3) Would you care to explain which ISP's ADR provider the OP should approach? If we assume AAISP, not one of the earlier ones, how he does that without either the eight week wait after they tell him they aren't going to bother, which they haven't done. Quite the opposite in fact, as publicly stated by their representative in this thread. Nor obviously is the OP likely to be receiving a deadlock letter, for the same reason.
4) Given that the ADR system is for resolution of disputes between an end user and their Communications Provider, and the OP has no dispute whatsoever over this matter with any of the ISPs who have tried to resolve it, why have you made such an irrelevant suggestion to be used as a final resort
