Utter poor service at Hyundai Tygervalley- Capetown

The most pathetic dealership ever! Bought pre-owned vehicle, only on collection was informed about a clutch problem, and visible dents and scratches. Car collected on Saturday, drive from Dealership experience other problems, mechanic drive car on Sunday list car idling not right and it miss, which I was not I formed about. Monday morning send salesperson message listing problems. 2days go past without communication from them, they don't answer to my emails and I don't get through to them on the phone. DP don't even respond on emails after requesting feedback. Speak to DP only after a week on Friday after he was cc in previous emails, he promised feedback Friday still, it is Saturday and I have heard nothing. I have not even received a copy of the contract, number plates and spare key was said it was gonna be courierd in the week, still nothing, and who's responsible for putting up the number plates? The customer? Utter, utter bad service from Hyundai Tygervalley- Capetown
