I have a 7 on order as well, and a presumptuous Tesla employee changed me to a 6 and added 17k to my price without authorization. After "nicely" explaining the situation to another Tesla rep, they reached out to the regional managers and let me know they approved going back to the 7 for my "grandfathered" pre 17k hike price as it was not my fault for the initial change. They also said the approval is noted all in the notes when I spoke to multiple Tesla reps, but that the price would change/reflect once a VIN is assigned since currently its back to a 7 but with 17k added on still. Sounds maybe similar to this, so I have my fingers crossed that this is true
