FSP43308

My mother bought 2nd hand car @ benoni. After 2day, we saw oil leaks n aircorn not working. Which sales consultant did not declare any faults which by law they were suppose to.. After week we took it back and they even confirmed with other consultants. We left car and asked for refund. They told her about 7days process. We waited for more than a month plus.. I went the n spoken with owner of car dealer and they said, they are registered by they dont have any processes of refund and they dont have money to pay us back. They gave us another month to wait and promised to pay us.. If not ill open case and i need help with reporting FSP business with no process and act on regulations of car dealers...
