If you have a complaint with one, it would be a consumer affairs bureau under the state Attorney General. You can go to them directly. If its a new car dealer and teh vehicle is the brand they sell, you may also try calling the car company that the dealership sells and services. They will usually respond pretty promptly, at least the GM and Ford ones do and I would expect the others to as well. They want you to be a repeat buyer. Good luck.
