You may not like it, but he is correct. You have only one path to the Ford reps, and that is through the dealerships.
You might try calling Ford Customer Service, but essentually all they do is turn it back to the dealer for them to respond.
I'm not saying that I like the system, but that is how it works. You need to try to always get the dealer personnel on your side. They are your best ally. Your chances are much better if they go to bat for you. Sometimes Ford just will not be moved though.
