This is going on for 2 years. I live in Brooklyn NY, in a 6 stories building. Here are the issues: Excessive amount of noise coming from neighbors above. I've called over 60 times to 311 and Police, and I have proof. I sent 3 certified letters to landlord and he has not responded. I've tried talking to the neighbors yet they were extremely rude and threatened me. Lastly, I sent them a letter. I called Brooklyn House, DHCR, NYC 311, Police Department, and Consumer Affairs. I don’t know what else to do. I’ve invested so much money in this apartment and I love it. I live with my family here and this is a perfect neighborhood. What can I do?
