They stole my deposit which was double my rentals

Worst Property Management Agency ever, I stayed there for more than, left a 30 days notice, even sent it to them twice, I paid double my Deposit which was more than R12 000, and got 0 cent back. and their excuse from Clinton, one of their agents there, was that I didn't give the 30 Days notice, which I gave him, and countless times failed to get into communication with him, rather via calls or emails. This Agency stole my money, I would never recommend them to anyone. If only I had time during the week, I would have taken them to court. Am still ****ed and will forever be at them.
