They have promised in writing a job for $350 OUT THE DOOR! and then later they jack up the price charging a 5% "Shop Charge". After the car was halfway done. they decided to charge me for another $100 telling me i need a "module" in order to complete the job. since the car was already halfway done i had no other choice but to pay $100 for them to complete the job. I have invoice in writing for $350. but i end up paying $500!!!
