Can I change front door lock as they have threatened me and wont return my front door key or mailbox key . I ask them to bring police with them to get their belongings . I am in fear of my safety . They were ask to leave as they were dealing drugs . They were renting a room which is still locked with their belongings . I do not have a key to their room . They all so own back rent . I really don't care about that though . I just want to change front door lock so I can feel safe and beadle to leave my home without worry they will rob me .We offered to let them back in with rules of no dealing. She refused, and told us she wasnt coming back.She has been moving her stuff out little by little but only when someone is here with me. I have not left this house except to run to corner store, which takes 5 min. She has already taken things out of room that is not hers. Things that are mine. She has also left her Kitten and dog behind and yes I am taking care of them as my own. Did that when she was here also as she wouldnt feed,water or walk them. Please I need some kinda answer. She is in my neighborhood as I type this.
