Usually the top line says Model 3 Performance so you might want to ask them about that.

Yeah but this OPs line items clearly show "performance dual motor all wheel drive" for the same cost as you have on your MVPA, so OP clearly purchased it.
OP I suspect you are correct that they never corrected your account properly. I would get your MVPA out, along with that sticker, and contact tesla about your car incorrectly showing up in their system. If you dont, you run the very real possibility of more headaches when they incorrectly "correct the mistake they think they made" in assigning your car performance software.
Since you have corroborating evidence you purchased this, it should be fairly simple to make scans of it into PDF , and contact them to get it corrected. If it were me, because I like actually talking to people in person who can make decisions, I would likely do the following:
1. Make physical copies of my MVPA, as well as PDF copies.
2. Drive down to a tesla delivery center, the one closest to me, in person.
3. Ask to speak to a manager at the delivery center, for "help with a specific one off problem I was hoping they could help me with".
Explain to the delivery center manager that I bought my car as one of the first Performance version cars, without the performance upgrade package (I would not use tesla forum lingo like "stealth", but use tesla official descriptions or as close as I understand them). I would say that, in my online account it does not show as performance, and I was recently offered the acceleration boost which I know is not applicable to my car. I would say "Here are the copies of the proof I purchased a performance vehicle, and I was hoping that you could escalate this for me through the correct channels, as I am not sure where I should go to escalate this issue?"
I would imagine that they should either escalate it for you, or give you the specific email address you would need to escalate it. I prefer doing stuff like this in person, because its harder to ignore you in person, and its easier to explain exactly what you need, while being polite about it.
Thats what I would do, but I definitely would NOT just sit on it, because its likely you would then have to figure out how to escalate it when they turn it off for you by mistake.
