Arrogant Neighbour

Hi I m suffering from very bad and illiterate neighbour. They shout they scream purposely in front of my window and door and whatever things i keep outside they throw it here and there. I stay in a rented house before i used to close all d Windows and doors to avoid them bt now it feels me very suffocated to keep d doors and windows closed. So i keep them open i have a 3 years old kid and a 4 months old baby which they get disturbed because of my neighbour's screaming and shouting.spoke to the owner bt of no use he said even he is fed up of them and want to remove them bt they r not going. They do this with every tenant who comes here we are the 3rd tenant with whom they are fighting. Again today when we asked them to stop all the noise he started fighting with my husband and started abusing him with very dirty language and he called 2 local gundas to beat my husband. They were trying to come inside my house bt we stopped them smehow. They also gave threats of like u meet me outside i'l show u. Dont take panga v r very jhagdalu people. Need serious help
