KIA Somerset West POOR Service

Very disappointed in KIA Somerset West bought my second car from them a little while ago but from the get go we experienced issues first it was the breaks that was absolutely shot i reported this to them and they did agree to replace all the pads and 2 x break disks GOOD! then the tyre company showed us that the shocks was also leaking and that all four tyres was very close to end of live , now I understand that buying a second hand vehicle sometimes comes with issues but this car only had 40 k on the clock and it was made clear to us that the car went through all the checks with KIA mechanics and everything was perfect so how can all this go wrong with a car that was apparently checked by KIA own mechanics , all the sales man can say to us is he only sells the vehicle those things got nothing to do with him Pathetic
