The dealer does not want to refund me my money after bad service

My Name is Gloria Tshidi Bookholane I am kindly asking you to please help me to get my money back from Hyundai Benoni. I paid R349 900.00 cash for a Hyundai Tuscon 2017 on the 7th November 2018 via Standard Bank. The car was only delivered on the 12th November 2018. When inspecting the car, there were damages I took the car back the following morning. I showed the manager he took the car and said the salesman delivered the car without his knowledge. Can you imagine? I emailed the Head-Office for intervention because I lost confidence in the dealer. Realizing the delay caused by the Head-Office I phoned them they referred me back to the dealer that I don’t trust. I feel as a complainant the Head-Office was suppose to come back to me what made me to take back that car to avoid that it doesn’t happen again guess what the response of the Head-Office was. I can go third party arbitration which I find to be unfair. Hyundai is not the only dealer in Gauteng. I prefer to have my money back and go to other dealers.
