Basically I have a mate who lives on her own in the lower flat. she has had a new tennant move in above her and she has been playing music very loud all hours of the day/night, this lady has a baby and seems to neglect it, stomps around her flat and generally acts like a complete twat. Its keeping her awake and her child awake at night and she rarely gets a good night sleep.

The council are failing to do anything, so is there any tips or suggestions to getting her to shut the fuck up or silence her through canny legal looking letters?

Any help, tips, suggestions welcomed cheers.
