Deposit Theft

I have called the head office a numerous times and I have emailed the below with no response and people hanging up on me. Luticia Brown<***>,Francois Retief <***>,Colleen Nielson <***>,Sifiso Mpisana <***> Today marks 21 days since I moved out of Unit 49 Stanton Heights Brentwood, Benoni. I am still waiting for my deposit, last week I called and I was told the maintenance guy was sick and only coming back this monday and he will get back to me. Two days later I have still haven't heard or received an email from Igrow Investment. When you call you are told to give you details and someone will call and that does not happen. So I want to know what it will take for such a big company to me my money back? I am annoyed by the service and lack of communication, but your team was very efficient when I was moving in, now that I am out and you have you to pay me, no one is saying anything. This is definitely my last attempt, I guess my money will start accumulating monthly interest from you guys.
