Tenants complaint constantly about their safety, due to apartment manager keeping a maintenance guy who has threatened tenants and their children and even their pets. We are told that all we can do is write an email and nothing has happened. Basically kept a prisoner at my own home, because I cannot afford to move. Feeling like my safety is not being taken seriously due to them Cirrus Asset Management not caring about tenant concerns. How ever I have taken it in my own hands and started to visit a gun range to protect myself from this guy if I feel threatened again.
