Renault Triber Dynamique zen

I am so disappointed in Isuzu Vereeniging . My car was involved in an accident and my insurance purchased a replacement car from them , the car was at 24 800 km but started overheating and had a crack on the water bottle. When I requested the car to changed I was taken from pillar to post. How do you sell a car that was not inspected and then act like you don’t know that the car has a problem. I don’t advise anyone to buy a vehicle from them .
