Bad Service, No deposit refund, ***********

I have been waiting for mafadi to refund my deposit for over 26 days. when I call no one is available, no one is communicating with me. And finally they deposit R1800 in to my account which they should be refunding me R4000 cause I left their apartment in a good condition. Sihle is never available to talk to me regarding my deposit. no one is explaining why my deposit is not being paid in full. the contract states that I should be refunded my deposit including the interest. I've sent Nandi an email, explaining my situation, complaining about sihle being ***********. Nandi replies to my email telling me that the orchards is not her property its sihle's. she is referring me to the same *********** person when she should be dealing my complaints. No one is able to help me as there is finger pointing and lack of available people to sort out issues. Shannon is apparently sihle's manager but she's forever unavailable and not returning messages. I just need my full deposit refunded to me.
