Smith Golden cars

I bought a car from them last month in their branch in Johannesburg Betrams (Smith Golden Cars)and within 20 days of having the car the car broke down with issues that are related to the previous that they never disclosed to me. No one is willing to assist f4om the dealership. As I am talking now I have a car standing and waiting to be fixed while I have a debt hanging ovee my head. I have not even paid the first installment. The car was financed by ABSA and the bank rep has failed to assist too but just referred me to the warranty of the car. I feel ****** by BNA motors. I will never deal with them again.
