Rust on doors / Dispute

Hello, like so many I have serious problems with the unfortunately already typical rust on the door folds. I have it with my Mondeo on all four doors. On the left rear door even the varnish with primer has remained on a length of about 10cm on the door seal. Now everything is bare and rusts nice (top galvanizing!). After Ford had promised me an answer to the further procedure before Christmas, I finally got this week the message that the doors on I don’t agree with the solution at all. I don’t see it anywhere that a car in this peis class (NP about 30,000€) and one of Ford’s promised “extraordinary high quality” on the doors should be gammelt and only painted. What does it look like when sanding with the galvanizing? Do you look at black metallic color differences in the painting? Problematic can also become a resale. Price discount Selling a car in the price range where it was repainted at the car body. A protest with my dealer shows no success, because he is allegedly bound to the factory. I see here only the possibility of a dispute. Now my question: Has someone with the same problems resisted Ford, possibly even started a dispute. What experiences did you have? Greetings and good driving
