Lack of investment for sure.
I have the perennial wet weather problem. Crackle on the phone line, poor/dropping internets some time after its rained., like.... NOW!
I'm with Talk Talk and I can now quote their script sheet verbatum but I do end up being passed to second line support who confirm they can see an "issue" with my service. By the time OpenReach get there the conditions have stabilised and they can't detect anything...... sigh....
Except this one time. The engineer turns up, he's outside the house for quite a while and says the problem is 100% definitely the outside wiring, its not in any sort of cable run, just buried in the ground. He said maybe its actually perished, maybe a root is growing through it. He said he can do a short term fix, patch a cable above the ground for the poor quality section or get the cables dug up. He would just have to check with his manager what he was allowed to do.
He goes off and checks, thats the last I hear of that diagnosis.Next engineer doesn't know that the last one had visited, he goes through his checks but I could tell that he was nowhere near as thorough as the previous one.
All I can do now is build up a history of stating crap service when it rains. Maybe one day there will be enough evidence for them to spend some $$$. Maybe.
