Very sorry to hear this. Not good.
It sounds like you have a relationship with your DS of some sort. If I were you, I'd let your DS know you are not happy having done Tesla a favor, now at your major expense, and you expect Tesla to make that right in addition to providing a quality vehicle as promised. I'd ask his/her help with who you should escalate to, then go that route. If you don't get a name or number from the DS, I'd start up the chain on my own. IMHO! It's better to get the plan sorted out now ,vs when your MS is sitting ready for delivery, you're wanting to take it home, and perhaps more willing to give leeway back to Tesla that you shouldn't really have to. Good luck!!!
So I tried to contact someone in Freemont and they have basically walled off all operations. There is no way to talk to anyone of any significance over there.
