Don't buy a vehicle at Mahindra Pretoria North

I bought my car in July 2022 (Jeep Renegade) and it was delivered to Cape Town. Everything was promised e.g. full tank, full service etc. When the car arrived it had zero fuel in the tank, the service also wasn't signed (could've been an oversight), but they promise they serviced the car. I had to redo the roadworthy as I missed the date to register my car and they discovered a leak on the gearbox. I took the car to the Jeep service centre and diagnostics test showed leak on tappit cover and leak on vacuum pump. Now you tell me, IF the car was serviced when they said it was, wouldn't they have picked this up? Also, how did the car pass a roadworthy test when they did it? I now have to fork out my own money to fix the repairs as the dealership is just 'shrugging their shoulders'. Therefore, I'm rating that this is the worst experience I've had with a dealership. All they are out to do is to just make a sale, get the commission and move on.
