My new neighbours moved in a couple of months ago (beg Feb) and the day they moved in, I had to call the police as the new neighbour was threatening to kill the ones moving out. The police came and things seems to calm down.
I contacted the HA on the same day to complain about them. I didn't hear anything back and in the meantime, my neighbours kept coming over to my property with letters or about other things, like works going on in their house. I didn't hear anything back from the HA and called again and they had lost my initial complaint so I complained again and included the neighbours constantly coming over, sometimes twice a day.
I still haven't heard from the HA but called again and they are apparently investigating but they haven't contacted me. My neighbour came over yesterday afternoon when I was in a meeting on Zoom. He knocked on my door and when I opened it just kept saying my name. I said 'Is this urgent as I'm in the middle of something.' He said no but he'd be back later. I contacted the police and they said they would put a marker on my phone and to dial 999 if he becomes aggressive.
He didn't come over but I'm not sure what to do now. I contacted the HA today and told them that he came over and gave them the police ref. I'm now thinking that I'm not going to answer the door to either of them again. Any advice?
