If it was me, they would reflash it back to the way it was built. They might cuss me a bit, but they would do it. I can cause a rightous scene when need be.
Be calm, talk to the service writer, when he says no, demand to speak to his boss. So on, up the line, till you get to the guy that owns the dealership. If he says no, inform him that you are fixin' to start disturbing his customers if he does not satisfy you. You are simply asking for your truck to be put back the way it was when it was brought to them. After about the third person, start raising thhe volume with each additional person. But never ever get mad. Works every time.
