Same here. Who did you talk at ‘customer support’? I’d contact your OA, mine was the best person for paperwork not having to do with the actual pricing of the car (the IDS did what was on the website, documents, getting a price updated for recent cuts).
The OA is in the local delivery center (as opposed to the IDS who is in Vegas for Model 3’s) and seems to do ‘owner stuff’ (duh?) like referral codes, etc.
I’d not call generic support unless you are doing the change order for the off-menu items. Yes, it’s a major mess.
But every report (see above) is that recent orders will/should get the 6 months of supercharging.
