I've been living in my apartment since the end of August. My landlord told me that the keys would be delivered to me by the end of the week. On two separate occasions, I have requested the keys, and each time, I have been told that they would be there by the end of the week. My housemates and I cannot lock our door when we go out (we all go to school and have jobs, so the door is frequently left unlocked), because none of us have a key or method of reentry. One day, I even came home to an unwelcome guest waiting for me in my home (DV situation). Since our requests for the keys have been denied, what can we do?
