Well, I know getting mad, or arguing never gets you anywhere. He said basically I bought them from another party. The boxes the trim come in do not seal, they have a folded flap that closes them, so his point was anything could have happened at any time. He did not say it was not their fault, just said it may not be their fault, either. I agree with you COOP that here is a great time to step up and show some customer service. What would they be out? But, it is neither my or your call to do so. I would gladly send this spare piece back in exchange for the right piece.
I told him I was not looking to get "something for free" or anything like that, and that the trim pieces ($350.00) were basically useless missing 1/3 of them. He said he understood, and would try his best to get me squared away.
If worse comes to worse, I can have my original right side rechromed, but that would probably cost me at least 100.00.
