That type of behavior is illegal! Have a friend try to set up an appointment with the same vehicle information and problem as yours. If it's no problem for them, something's afoot! But if a garage doesn't want to work on your vehicle for whatever reason. I wouldn't go to them and give them my hard earned money anyhow. They don't deserve your business! HTH. -Jim
There is a website, mechanic black list. They also list your phone number.
