I need answers from We buy cars.

My partner and I bought two cars from we buy cars, one from Germiston and the other from The Dome. This was in 2021 and 2022.We have a chevrolet and a ford focus. The worst experience!!!and what hurts me is that both cars are financed and we are now stuck with this huge debt and useless cars that require fixing every now and then. Both our cars have had engine issues, cambelts have snapped and the ford doesn't even have a catalytic converter and the car didn't come cheap it was over R150k. I would like We buy cars to answer and let us know what should happen and if possible I'd appreciate it if they took both their cars and gave me a car that's in a perfect condition or sc**** off my debt because they sold me lies. As I'm writing this the ford is in for repairs because the cambelt snapped when I was on my way to work this morning and I know that the warranty will give us issues aswell so I'm car less. To anyone who wants a new car DO NOT GO TO WE BUY CARS.
