wow cant believe i only just read this. I had a neighbour exactly like this and i lived with her complaining for 4 years with constant visits from the police and any other council dept that would listen to her (they would refuse to deal with her after they investigated me found no case to answer and subsequently she would get passed between environmental health, housing, asbo depts etc).. She complained about all the things you said, called the cops on me BEFORE I'd even moved in when i was decorating, stand outside abusing and shouting at me and my guests. There is so much i can tell you but i haven't got time at the moment but i can assure you it was all the same. Meanwhile i took every measure to kerb my "noise" bcoz i felt bad. What made it worse was that she was an old lady and she looked ill from the stress I was "causing". Two times it got too much for me and I'd bite back, then spend half hour crying on the phone to my mom bcoz i was worried I'd give her a heart attack. Eventually the council threatened me with an asbo. I told the council guy (new case worker) i would only attend a meeting if he investigated all the complaints she'd made to the council and cops and what the outcomes were and that my dad and her daughter had to be there. He duly did this and had a much better attitude towards me next time he rang to set up the meeting. Apparently she not only gave me hell but the tenants before me and also had been moved on from previous address bcoz of same problem.
Meeting was held during which, instead of being the frail old lady she normally portrayed herself as to council reps, she showed her true colours. In fact the guy had to restrain her twice. She admitted harrassing me for 4 years and also admitted the only noise she could hear was me going out on to my balcony and closing my front door. She admitted she couldn't hear tv or music or anything else and her daughter was shocked by all the crap she's given me and everything I'd done to try and stop my "noise" including not flushing my loo after 9pm.
The guy threatened to give her an asbo instead if she carried on. I'd like to say this solved the problem but it didn't although it did calm things down a bit. I made an agreement with the daughter that i would phone her if things got too much but then even once had an argument with her bcoz her mum was charging her electric mobility scooter off the communal plug while i was at work and she didn't believe i was paying for it (until i showed her proof) and proof that I'd also asked for the council to supply her mum with an independent plug (as i knew it was difficult for her to charge it in the house) which the council had agreed to , but the woman had refused to have it when they turned up!! Eventually the council moved her... Only to give me a worse problem (kid out of prison, drug dealer, wrecks the place etc) so it was truly a case of better the devil you know.
So what would i advise you do? I would advise you this.
1. Understand you are not the problem, she is.
2. Do not pander to her tantrums, it makes them worse, do not tip toe around your flat or continue to whisper, live as you normally would and don't feel bad about it.
3. Do not speak to her in any way.
4. if she turns up ranting, shut the door on her and call the police and tell them your neighbour is harrassing you. They may not want to come out but ask for an anti social behaviour crime number.
5. Log the harrassment and keep complaining to the council and give them the crime numbers ,(this is their proof of her bad behaviour) Set up a meeting so they can explain to her what she can and cant complain about (chances are they know already SHE is the problem).
6. If the council do move her pray you don't get a worse problem with the next tenants .
i fully sympathise with you bcoz unless you've lived like this, people can't understand the stress it causes, but i understand, which is why i implore you to accept that this is what she loves to do, it gives her power and the best thing you can do is tell her don't care, continue to live as you normally would (without whispering or tip toeing, put your tv back on sound etc) and refuse to engage any further with her without someone from the council being there.
