Just butting in for a moment. If you told them to do the work "so long as the supreme MAP covers the work" then they had no right to continue if they weren't confirmed on that. If they plugged ahead and did the work and MAP wouldn't cover it then they made the mistake. What they're doing is covering up that they made a poor decision to move on with your work regardless of the final word from MAP. BBB is a good start for the local shop. Making the phone call Rambit said to make might help too. The manager you talked to was the service manager or the general manager? If it was the service manager, have a face-to-face talk with the general manager. He might not be aware of the service manager's lack of attention to your problem.
