Deceptive dealership: Rusted chassis, hidden history, and wrong mileage

The sales process at Milnerton Nissan was incredibly fast when they wanted my money, but their aftercare is non-existent, sales lady ignoring my disappointment and never apologized for the mistakes. Shortly after buying, I discovered the Fortuner's chassis is rusted all over. When I complained, the manager promised to fix it, but they just did a rushed job and did a half decent job missing parts of the chassis.To make matters worse, they completely hid the vehicle's history. They never disclosed that this car came from Namibia, and judging by the leftover stickers inside, it was likely an abused fleet vehicle. On top of that, the car was delivered with almost 2,000 km more on the odometer than what was advertised. Milnerton Nissan used deceptive tactics, hid major defects. Do not trust them with your money.
