Bad service and theft from Mafadi Property Management

I app**** for a flat at 17 Black ******, 240 Main street Johannesburg and was assisted by Luvuyo Maqaqa who misinformed me with regards to the occupancy date for the property in order for me to pay the deposit. I was supposed to have occupied the apartment on the 8th June 2018, when I went to go fetch the keys, I found that the building is not habitable as there was construction still going on. I eventually cancelled the lease due to false information and bad service from Luvuyo. Now, they are giving me the run around with regards to my refund after they gave me a stinking service. Mafadi and Luvuyo Maqaqa owe me R9350 for the deposit I paid.
