My upstairs neighbors wake me several nights a week by pounding on the floor. They claim they can hear me snoring. I do snore occasionally, but I've had two surgeries over the past year and my girlfriend now says she almost never hears me snore. I've asked my neighbors to stop and have even purchased for them, with my own money, a sound machine and ear plugs to help them sleep. They've refused to change their behavior. I've also complained to the landlord about the situation several times, but he refuses to do anything. Do I have any recourse here? I have no idea what else I can do.
