Sold an unsafe car to us!

On Tuesday afternoon, 18th Feb 2020, we purchased a vehicle from the 'We Buy Cars' Phumelela Park Branch. We drove the vehicle home and realised that the car has a water leak. We contacted them immediately and told them about the water leakage issue. They assured us that they would contact us and never did, so we contacted them again and to our surprise and disgust, we were told by both the salesman, and the MD of the branch, that it was not their problem and we were to repair it ourselves. What a disgusting way to treat a customer. What if we had broken down on the way home????!!!! 3 woman alone, 1 heavily pregnant!!
