It has been a year since I moved out of one of there apartment complexes they owned (they changed company's around the time I moved out) and have yet to receive my security deposit worth 1000$. I have called on multiple occasions and either have no one pick up, or they hang up on me. The last time I called they redirected me to someone and as I was about to leave a message it hung up on me. I also emailed the person and never got a response.
