Kia Multi Franchise Nelspruit

After the previous complaint I submitted. Nothing was done. I towed my car back at my own expense and the car's clutch was damaged, even though when I sent the car to their service center, it was not damaged. Please help me to get this sorted out. They did not explain anything to me what happened to the car. Their service is really poor. I would not recommend anyone to use their services. Their contact number is 013-7576000.
