Bad Service at Kia Randburg

Good day

I would like to bring your attention to the following issue am facing with the service I received from Kia Randburg. About a week or so I brought my 2013 Kia Optima in for having issues with power performance,, after checking the car for a few days I took the car back with the agreement that when the service centre is able to find the part that we can test with than I will bring the car in which is all well. Now the problem I am having is that on that weekend when I drove the car during the night, it come to my attention that my park lights are flashing on and off automatically in which this never has happened. I than brought the car back thinking that you guys didn't plug them properly but sadly I was informed that my switch is faulty and that it will cost me R200 for a new switch and R900 to install it. As I was trying to keep a good relationship I thought to not fight and thought I could solve this problem later on but sadly my problem has escalated to the point that I had to call my insurance about 8 times in 8 days cause my battery runs flat and my park lights keep on flashing on and off

I have raised this issue with the service centre and all they can say is that switchs get faulty and I have to now pay R1 700 for a switch cause the 1st time they gave me a wrong quote. I feel that the service I received is not up to standard and the switch was damaged when the car was in their position and now I have to bare the cost.

In which I am not willing to do so cause they damaged the part.

Regards
