No, you are lying.
I have to say that I did not expect that from.you.

No. I provided hard proofs while you are telling tall stories. As usual. Don`t worry, we are used to it. :):):)

COUNCIL Lol, waste of time complaining to that lot.

I've had an issue with poles that is still ongoing due to noise, damaging cars and burning rubbish out their back garden which in turn fills my home with fumes, the council were very keen until they realised the neighbours were poles then all the council could say was, "its intermittent so can't do anything about it"

Police are the same, everyone is scared to offend and my neighbours certainly know how to play the victim card.

You are a very stupid person.
Go and talk to them, enjoy a drink together and maybe share some food.
Once you get to be friendly with them, raise your concerns.
I guarantee that they will be sympathetic and will comply.
Your negative attitude is the problem.
