Before getting into legal things, I would say dont talk to them directly cause it is not your job, go to the apartment office and explain them the situation and tell them you have told them regarding this issue and they have said this and that.. let them know you didnt want to contact them any further because they might create fuss. Usually aparment company will contact them/ send them letter or tell them to move or gives you another choice (apartment). so dont talk with them..first of all go to the apartment office and talk to the manager.
