Ithemba property deposit refund

After having evacuated their property in September 29th 2020, with an agreement that my deposit fee will be refunded back to my account within 30 days effective from the day I left the building. To this day I haven't received my money,all I get is endless excuses. I received a communication from them on Monday the 2and November 2020 via email after endless unsuccessful telephone calls which assured that the money will be paid in on Friday the 6th November 2020. This is now 37days overdue,I'm not happy with their pathetic service rendered even during my stay as a tenant I experienced poor service . Please assist me resolve this matter because I am tired of this run arounds.
