Buying a faulty car wich we where told will be fixed

We just purchased a vehicle from wheelee in Centurion first we had to wait 2 weeks after signing for the vehicle because they apparently had to fix the car first after waiting 2 weeks and receiving the car and being told that the car will be almost as new on the way home the car went into limp mode having no power at all and bringing up warnings that the oil is to low and we cannot exceed more than 4000 refs on the engine then 2 days later the clutch started making noises after they told us that the clutch plate has been replaced if I wanted to buy a car falling apart I could gone have bought one on auction but a person pays alot of money and expects a car that is reliable not falling apart this is totally unexceptable
