Bad car dealer

My son bought a vehicle from Marius Pretorius (2 weeks ago), he is a car dealer in Brackenkell. He had the car for 2 hours then the car broke down and had to be towed to a service centre. After my son paid a lot of money to fix the car the car is running again. I wil never recommend him to anyone!!!!!! I cannot think how someone can run a business like this. I think he must be responsible for fixing the car and must pay for the damage.
