Interesting - I had to resort to council help with a previous neighbour who insisted she had the right to play rubbish loud music (Radio One, which I despise) anytime she pleased. The only time I tried to resolve the issue politely, I got a door slammed in my face, so I had to ask the local council for help. This continued indefinitely for a long, long period of time, during which I had her accost me in the street to scream rude names at me, and also had my Traveller (previous to 'Ector) being abused in various ways (I had no off-raod parking then).
Eventually we sold the house and moved on, and I later learned that said benefits-scrounging antiosocial blight had been forcibly evicted from her nice two-bedrromed council house that my taxes had most likely subsidised and forced to get a job.
So I've seen it from both sides. Nice to know there's some justice in the world, albeit rather late, so don't worry, if anything happens it will take a lot of time - speaking from personal experience here - to get anything done, and at least you are the sort of person who regards others with respect, rather than contempt as my previous neighbour did. So good luck, and always be considerate and polite.
I've had way too much wine to be posting on here tonight.
