QC checks not done, only money been taken

An second hand vehicle was bought from Secunda Toyota, the vehicle had an QC sticker on it, soon after receiving the vehicle there's been problems with the water pumps, cover plate etc. After these then again a loose pin that cost R15000 which another call was made and furthermore inconvenience this deal was a cash deal so the dealer appreciated the money but there was no quality check. Due to this I am left without an vehicle and now the dealer is putting his hands in the air because they can't do anything. This dealership should be overlooked and no deals to be done with them
