I work for a DC company and can tell you I would keep going to the CEO of DC in Germany if that is what it took. Keep in mind no matter how mad you get, being rude to someone you are asking for help from isn't the best approach. I would for sure try another Chrysler dealer and send a letter to the owner of the first one and let him know about his store's customer relation skills. The trick is to stay on it, the squeaky wheel will get greased, just keep on squeaking.
