Given the issues of violence and threats that you have received recently at the apartment complex that you reside in, I suggest that you have a face to face meeting with the property manager to try and resolve the situation to your satisfaction. Follow up the meeting with a letter memorializing what was stated. Keep a copy of it for future use and need.If the result of the meeting does not meet your satisfaction, you should then consult with a landlord tenant attorney to discuss what your legal options are.
