Sold a car that was in an accident and was not disclosed

We were sold a damaged car that was in an accident,and is currently falling apart and still under finance. We had raised the issue with the salesman,Linda Sekwa and we were dismissed. The car has been faulty, and now in bad condition. We took the car in to another garage,and we were told everything in the car was not original and the car was in an accident and has been put together. The manager Zenzele Nceswa also dismissed our complaints and told the car is fine. We are tired of paying our hard earned money for a car that is bad.
