I don't know where you live, but you should investigate Lemon Laws in your jurisdiction. In the meantime, keep going up the ladder at GM. Service Experience advisor is an entry level position at GM, and typically is filled by new hires that know nothing more than what the rules tell them to do. You need to get to someone who has the discretion to make a decision. Obviously what you are being told does not make sense, and is completely unacceptable.
Oh, and shame on you for not pressing the issue while it was still under warranty.
