Poor customer service Paarl Auto Pedigree Managers

I bought a secondhand car through auto pedigree paarl. I had great service from the salesman.,but a few weeks later i noticed the service light went on... I got in contact with the salesman. He than took my car in to get it checked out. They told me it was the throttle body, but than i told the salesman, they should replace it, but just said its not necessary. A few days later the car done the exact same thing. I told the branch manager of paarl auto pedigree whats happening. I told him that you inconvenience me every time and that i want a car to get to work when the car goes in. He than said no we cant give you a car. I told him that i bought the car 2months ago and from those 2months i probably had the car for a month. If they hadn't sold me a car with such problems, i wouldn't have had this issue. They had to replace my brake pads. Tell me if you sell a quality secondhand car, arent your people suppose to check if the car is safe to go out. That was not the case with Paarl Auto Pedigree and their service centers.
