They lie and sabotage
When I went to pick up my son's truck after repair of half of the invented problem's they said it had, the air conditioner did not work.
It was fine when I brought it in. The manager swore they never even looked under the hood...then a greasy guy came running out with a pair of pliers saying, you need them to get the hood open...gee, how did he know that?
Another guy said they were out of air filters when I picked up, but when I complained, they found one, and said to go get it installed elsewhere...
