The end date for model 3s to have free unlimited supercharging on the performance version was September 30th. If your car was delivered after that, it didnt qualify. Since you didnt buy the performance package, you obviously couldnt get a refund on buying the performance package.
This isn't correct, exactly. If the ORDER date was prior to ~September 30th (originally it was September 19th or so and then it got extended for 10 days or so, AND you had to use a referral code to get it), then you qualified for FUSC with Performance package (upgraded package (brakes, spoiler, wheels) or not).
Delivery well after that date was fine (even into November, you still qualified). That's how there are "super-gifted" Model 3 owners, who BOTH got the $5k discount on their Performance Model 3 (with the Performance package, not the Stealth) AND got Free Unlimited Supercharging. They ordered by the deadline, with a referral, and took delivery after the price drop (which they got if they ordered the Performance upgrade package).
But you did have to
order prior to the date you mentioned, and you had to use a referral code.
Now, for the OP, it's very confusing to me the way he said it, but I think I interpret it to mean that he ordered the Stealth Performance (and if
ordered after September 30th he
did not qualify for FUSC as you said), for $5k less than the Performance Package, originally, but when the price change occurred subsequently, to Performance packaging being
included at the
same price as the Stealth, he complained and asked them to deliver him the Stealth at his same order price, but with FUSC included (which implies to me that he ordered at a time that did not qualify for FUSC).
He says they agreed to this, and added FUSC to his account. Probably it was removed in audit or something but getting this back is probably going to be a long road. It is outside the normal realm of qualification for free supercharging. I agree that really the only legit "flow" in his case (if he ordered after the deadline) would have been to take delivery of the vehicle with the Performance package included at his original price point (so adding Performance upgrade package for "free").
As you know, a lot of owners ordering before the deadline, and taking delivery (before or after the deadline) with FUSC and the Performance (or Stealth) package got upset about the $5k price drop on the Performance package, and were able to get $5k back in exchange for giving up FUSC. But that was
only for those people who qualified for FUSC.
There are huge detailed flowcharts dedicated to this, if anyone wants to recall the history; just have to search. It's entirely possible there's a few alternative flows I'm missing here, haha. I remember some of the charts claimed you could get "double" FUSC, haha, don't remember the exact qualification method for that.
