Bad attitude, poor customer service & bad quality cars

On the 19/05/15, I bought an H1 bus (used) at group1 hyundai Midrand. 48 hours later I returned the car because I picked up a number of problems on it and the dealership requested a week to address them. 5 weeks later the car was still sitting with the dealership because they had ran out of money to fix the car because of additional problems that were detected by their workshop. Realising that this car was bad news, I requested the dealership to cancel the deal or source me another similar car but they refused. The dealer principal started being personal and even **** to my attorney's and the bank that I had abandoned 100% car. On the 28/08/15, I went to collect the car and took it to Dekra AA for an inspection and another list of faults was detected. I discussed report with the dealer principal and after an argument he chased me out of the dealership like a dog and asked I take the car with. As I speak the car is sitting at a storage
