I had a VIN number (~31000) assigned a week ago with a delivery set for the Rockville, MD SC tomorrow. Received a call yesterday stating my pearl white, RWD, 18" Aero Model 3 had not arrived yet so they wanted to push delivery out 1-week. The new delivery date is Aug 8th. I also asked where the car was coming from, and the gentleman stated a staging lot near Birmingham, AL. Today, I checked the My Tesla account website to find my VIN number had disappeared. I no longer have any VIN listed, although I still have a delivery scheduled on the 8th. Not sure what is going on. Has anybody else experienced this?
