Hello people. I have a problem. I have neighbors under my apartment floor who have been banging my apartment for a few years. They are doing this because they say my family's footsteps are too loud. My apartment floor is made out of old wood, and if the footsteps are causing sounds, it's beyond my control to stop this. They have been banging to the point that I can seem to tell they are having fun doing this and they are following me sometimes to bang wherever I'm going. The banging is literally causing heart shakings and I believe health problems could develop. They contacted the police a few times in these past years with no effective solution and the banging just keeps going on. I was wondering if anybody know of any way to stop this banging.
