What you need to do is go into the service department at it's busiest time and make a scene.
Shout - yell - bang the counter with your fist and let customer hear that you are being shafted. It's probably even better if you take a female and get her to do it for you.
A service advisor once told Marie that she wouldn't understand why the noise in the gearbox of our new car was all in her imagination.
By the time she had finished with him he had been moved to spares - we had our own personal service advisor and they replaced the car.
Never underestimate the power of an angry woman
