I want my money back....!!!

This people do not know what professionalism is, i rented a car for 5 days in Maseru Lesotho and paid R3105. They refunded after 2 days, but on later stage they deducted another R3105 from my account of which i didnt know what was it for. I tried calling them several times but i didnt get any help, i spoke to their survey department and they promised to help me but they did not. I did send several emails to their head office in Joburg but even today i never got my money back.
