Auto pedigree plumstead wants to sell me a faulty car

As a business person i approached auto pedigree in plumsted looking for a STARIA Hyundai to be specific under finance , the got the van in Johannesburg and Wes bank financed it , the car arrived in Cape Town on arrival it had a lot of faults it was booked in at Hyundai Bellville , the technician that worked on the car advised that this car has been tempered with and the warranty won’t pay auto pedigree needs to pay they refund and took the van to their service . Today is day 22 the car has been with them fixing the issues on the car , I send the branch manager several emails asking him to either get me another car or cancel the deal because I had bookings for that van I had to refund people now I have to cancel bookings because the car has been with them for 22 days . That car was supposed to be working and I told them it is a business car . The car has been resprayed they never told us that the car has an air bag light according to the technician at Hyundai this car looks like it was in an accident the branch manager still denies that. I told him I no longer want the car his running around he doesn’t want to cancel the deal nor give me another car.
