Hyundai Pinetown... Selling damaged vehicles

I have a pending issue with Hyundai Pinetown which I've asked to be resolved. I have contacted them nearly every day for 3 weeks as the car they sold me has faults that needs to be fixed. Engine management light has been on since I took delivery of the vehicle.. Hyundai Pinetown has to be the worst dealership I've ever dealt with. The dismissive attitude and lack of assistance post-sale is beyond pathetic. Please contact me asap to resolve this as I will be taking this further.
