Kia Motors Northcliff Johannesburg extremely bad service

I purchased a vehicle @ Kia Motors in Northcliff Johannesburg (delivery date 2 August 2019) They sold me a car that: was not serviced, wipers torn, no brake pads, no shocks, noisy timing chain The vehicle started giving me problems 3 weeks after the purchase, steering wheel started to shake and it was due for service, I took it back to fix all the problems but they only did the service and brakes, Renault checked the car and identified all the above problems and they said Renault just want money.

As we speak, the car is stuck at a garage the fanbelt is torn, i told them that I no longer want that car because it’s been giving me problems since week 3 after the purchase. I spoke to the dealer principal Colin Thorpe and he agreed that they change a vehicle for me, I chose the vehicle from their stocklist and after they told me that I choose an expensive vehicle, we agreed that I should then check a reasonable vehicle for myself, I got it and yesterday the sales person Steven Bianchina told me that the dealer principal is saying that they are not taking their s**** car back. Please assist me as this car is only 3 months old and has been giving me problem from week 3 after purchasing it. I have also reported my matter to Ombudsman. Kia Motors Northcliff in Johannesburg have treated me very bad as a client, they have extremely bad service and doesn’t care about their clients for as long as they getting money and commission
