Waiting for answers for 3 weeks

In September I purchased 2019 Kia Picanto from Kia Hatfield. The service received from Sam was absolutely amazing. However, this vehicle was purchased cash. I was charged for a Matrix Tracker in the car, that was never installed. There appeared to be a problem with the clutch switch on the car, I noticed this after only 2 days when the vehicle would not start. I took the car to Kia Silverton, after a total of 7 days in the workshop for a car that had only 64km's on the clock, the vehicle was returned to me with a red scratch mark on the back driver side door, a paint chip on the bonnet, and a very deep scratch on the front bumper. I had requested Kia to either provide me with a new car or repair the damages to the car. Up to now, 2 weeks later, I no damages have been repaired and calls are not answered. I spoke directly to Wendy from Kia Hatfield pertaining to the refund of the tracker, I was promised multiple times that the refund has been loaded and processed by herself already, but 2 weeks later this is still not reflecting in my account, again, my calls are not answered. Kia Hatfield owes me R5000.00 for a tracker that was paid for and never installed. This is **************** and theft, not to mention the worst service. Althoug I love the car and think that Sam did an outstanding job, I will never purchase a Kia again.
