Huge sympathy. Re the council issues, in particular the rude response, you could contact James McCash, or whoever your local councillor is. That is just unacceptable from someone who is dealing with the public. Re the other, you could at least ask the builders to turn the radio down (or preferably off, though good luck with that, as many builders seem oblivious to the fact that there are people around who are trying to work or sleep or are ill or who just want to live quietly in their homes) . And you could try to find out when the work will be finished, so that at least you have some idea. And if there is actual damage, inform your insurance company as soon as possible if you think you know the cause, as possibly you could get this paid for by the building firm involved ( though I have no idea!)
