What are my options with a deceptive auto dealer repair, caught them lying about the entire repair.

my car suddenly broke down, took it to dealer, got complete run around called my car piece of crap told to go somewhere else, so this caused me several tows. I called the owner who talked to the supervisor. This time when I called back I asked about the stuff i was told the first time, was a complete lie, then I got back with the supervisor who suddenly will take my car without wait and warranty, he calls me saying they need 6 hours on top of the 2, days later calls and says its the ignition switch and steering lock needed to order parts, days after says doesnt start still found fuse box that is fried and needs to be replaced, when i pick it up the I find that the supervisor wasnt the one working on the car, the invoice specifically states they found the fuse box first then after they installed it found the ignition switch and steering lock, so clearly they found it all in far less than 8 hours and lied about the order to get me to pay more for unneeded work/ labor, they wont talk now
