Buying a second hand car at Hyundai Germiston dealer

I went there to buy a used car on finace the car was volvo in december 2019. There was a funny sound coming from the gearbox. I tried to inform them and did not take me seriously I tried telling them so many times. On13 January they said I must bring it to them for a check the car broke at work when I tried taking it to them so I called them. Raeesh was the person who assisted me. Even today my car is still getting fixed and I'm busy paying installment every month
