Horrible Service from Mafadi property management

I rented a flat at Germiston under Mafadi Property and I had to move out end of October after serving my notice I was told I will receive my deposit after 21 days. I didn't receive any communication until end of November and I decided to do a follow up with my caretaker and she referred me to the property manager Tonde who was very unhelpful and so rude .He told me to send him a message and he will only attend to my query the following day as he is not at the office. The following day he didn't get back at me and I sent him a message hoping he will reply and he didn't .On the third day after sending him an message and getting no reply I inform him I will escalate now because I'm not getting any help from him, he reply with the message saying `it is well within my right to do so '' and he supp**** me with the office number .I feel that Tonde doesn't deserve to be a manager as he doesn't know what is customer service at all and doesn't even know how to talk to people .He is such a disgrace to the company and I don't think I will ever rent a flat or refer someone to Mafadi Property.This is such an inconvenience and I don't know what to do anymore to receive my deposit.
