Auction nation is a ****

I purchased a car that was advertised as a code 2, paid for it and took the the car to fix. Auction nation doesn’t give the paper on the day of vehicle collection reason is that they are still doing paper work. When I got the NATIS I went to register the vehicle it was confirmed that the vehicle is a code 3 which means it’ can’t be insured then I went to back to auction and told them and Mr Juan Pienaar is so arrogant and refused to refund me the money for the vehicle even though the vehicle is still in auction nations name.
