Rental deposit not returned!!!!!!

I have been a tenant with Rawson Centurion for two years in Umthunzi Valley in Midrand. I was a good tenant, never defaulted and maintained the premises very well. I was due to move out 30th of Nov 2020 but by the 28th of Nov 2020, I was out and my departure inspection conducted on the same day. Now its 30 Dec 2020, I have not received my rental deposit back. Agents ignore whatsapps and emails. I have had it with these guys. I do not know how else I can get my deposit back but the treatment has been appalling to say the least. I do not recommend this agency to anyone and I will never bring my business to these guys. Such tasteless service!!!!!
