Kia Sportage problems

We went to Kia Airport looking for a good 2nd hand Kia Sportage, they were very quick to help us to get one at the price we asked for , but little did we know that there was damage on the front suspension, we have noticed that there is something wrong without them even saying something because they told us that the cars gets inspected by a Kia service centre and they did not pick that up, the car was then sent to Koenic Edenvale for repairs just so that the 2nd hand sales manager at Kia Airport told them they should not fix the problem as we won't notice that it has not been fix like they said they are going to do. The guy from Koenic even told us that the vehicle was in a major accident and that they have to straighten the chassis at a panelbeater, but we where not informed of that, we where told that the previous owner drove through a pothole and we do not think that a pothole can cause that much damage. Kia Airport then sent the vehicle back to Koenic Edenvale for another attempt to fix the Car just to get the car back with more damages to it, we where very upset and the only "solution" they had for us is to send the Car back to Koenic Edenvale. We cancelled the deal and asked them that we want another Kia Sportage but they just do not care and say that they can't help us but they where quick to give us a damaged vehicle.
