I moved into new flat at beginning of lockdown last year and it’s been hell. Most neighbours here are nice but real nasty one through the wall - who acts nice outside in front of other neighbours meanwhile she bangs constantly on wall, has her dogs cage hooked to party wall so every time he moves the cage bangs. Her 16year old son sings (screams) at top of voice for hours on end, and they have almighty arguments where they scream and swear at each other. After being woke out with their screaming and banging on wall at 3am I told them to stop, now it’s worse. They have a set of things they do every day, from hitting a ball off the wall constantly, singing at top of voice out of tune (honestly, I know he’s a child but it’s sooo loud and sooo bad) the dog constantly howls and barks (left up against party wall), and now they’ve taken to playing something that is like a low frequency that causes our ears to hurt and vibrates through wall. I’ve heard her screaming at neighbour on other side. It’s driving me mad, when I speak to her she just ignores me - any ideas on how to make her stop? Btw typical passive aggressor smiles sweetly when we pass each other grrr I want to punch her lights out we’re so seriously deprived of sleep I could cry - just what do people get out of being this nasty?
