I have been living at my place since february and since week 1 I have been dezling with my neighbour that lives upstairs. She has mental issuex and makes my live miserable. Cant sleep properly, I wake up angry and argue with my bf, everytime I get home from worknshe is making noise and gets in my nerves. Is such a a noisy person, she has conversations with herself and chokes herlself, throws her rubbish through her window, she slamms the door 5 times in a row very heavily just to annoy. She drinks at the front door and pees too leaving the stairs stinking. I have tried everything already with the council the police and letting agent but is a long process which none of them is interested in bein part of apparently. I would like to know if i can ask for a rent reduction until this problem is solved. I am moving out of UK in 5 months, dont wanna waste time moving out and all tnat for just 5 months, i just want to pay less as i live right underneath and im the most affected neighbours and also the onex who pay most, the rest are paying half of what we pay. What kind of letter should I write?
