I highly recommend anyone going through the same junk with a local SA call Tesla directly. I had to wait online over 1 hour, but when the guy answered the phone he was able to immediately see and understand the problem. He also confirmed the $3750 was already credited to my account or there on the account. He said he would update the MVPA properly with the discount and the signature. He also said they are normally signed, so he was not even sure why mine was not signed. I will confirmed when everything is actually fixed, but the whole thing took only about 5 minutes and the guy was fantastic.
Moral of the story is if your SA is clueless or non responsive, call into Tesla and they will probably help you out quickly after a long wait time. I could have easily just asked for the call back instead of staying on hold, but wasn‘t too confident I would actually get called back today. I am assuming everyone’s experience is going to be different depending where you live, but I can tell you in Baltimore unfortunately this is more common than not as many employees are not that great or part of a constantly revolving door.
