Poor customer service and very arogant salesmen

I experienced poor customer service and very arogant salesmen. I wanted to buy a "A" reated car from the Vereeniging branch. After 2 x days I only received finance approval feeedback, after which I had equire multiple times, I was also forced to take a mechanical warrantee. I then decided not to continue. I was adviced to sent the required documentation for the refund on my deposit paid and promised that I would receive my payment within 48 hour. I've followed up serveral times about the refund after the 48 hours, every time there was new excuses and lies told to me. After 7 days I tried to escalate the matter with their management and call centre, only to find out that the arogant salesman only submitted the refund request on the morning of the 7th day after the request and I need to wait again 48 hours. I requested and immediate refund and are not successfull only telephone calls from second in charge its not possible,tried to escalate the matter to higher and regional management, which I was told it can't be done, seems like this matters a hidden from top management and the employees are protected.
