I feel you...I'm in a similar situation with just a "slight" twist! My order day was Mar 8, 2021 and the current EDD has been holding at 8/7 - 8/28. Now the twist, we are going to be out of the country, from 8/13 through 8/26 on a cruise that was planned over a year ago. It never even crossed my mind that I may have an issue with my X delivery during the 2 weeks I'll be out of the country. Surely I would have received my X long before I ended up with a conflict.
I've been exchanging emails with the KC SC Ops guy and basically he's telling me "tough noogies" they can't hold a car, deemed ready to deliver, for more than 3 days. After waiting for over 500 days that is a total garbage response from the Tesla policy, especially given that my EDD has changed at least 10 times, probably more. To add insult to injury, I have a friend who graciously agreed to inspect and take delivery of the car while we are out of the country. I just found out today, that Tesla can't issue the paperwork for my trade-in or resubmit my loan request until the VIN has been assigned, which makes the pickup by our friend a bit problematic. While we will have internet on the ship, I don't want to spend my days refreshing the app over and over looking for a VIN so that I can then have the process initiated. I'm hoping that the ship has a business center where I could print out, sign, scan and e-mail back, but haven't received confirmation yet that Tesla can accept that.
Who would have thunk it....
