Hyundai Strydom Park

I purchased a 2nd hand vehicle from this dealer, the aircon control housing unit inside has broken 2 weeks after receiving the vehicle, upon returning to have this looked at, they advised that this broken by pressing the buttons. I was in contact with the dealer principal and they advised they can offer me a 5% discount on the R14 000 unit, I have then subsequently been blocked by dealer principal as they want to take no ownership for this. I would highly suggest not purchasing anything from this dealer.
