1 day old car completely bombed out - we buy cars uninterested

I purchased a vechile from Dome we buy cars.

I had the vechile for a couple of hours and noticed that it was over heating and the water bottle was faulty. I had the water bottle replaced, it still leaked. The cause of this was because of the pressure. It was too much for the bottle to handle. I then was told that the water pump was broken, the head gasket needed replacing and the camshaft.

I returned to we buy cars the following morning after purchasing the vechile. where assisted by the manager Patrick, I was instructed to leave the car there with no other means to get home. Patrick was uninterested in my problem of getting back home.

Also told that they would prefer to reimburse Absa bank instead of having the vechile repaired. Dekra report mentioned nothing of the above.

How do you sell a car like that and then just withdraw the whole application, affecting my credit score. Also, it is already insured and payments to outsurance have already been made.

The next person to purchase if pulled back will have the same issue without them having it fixed? How does this at all make sense???
