It isn't clear whether the referral I got from my friend worked (I didn't use the link, but asked Tesla for the referral credit, and my purchase showed up on my friend's account). I used a few superchargers driving the car home, but there was no indication it was free. There's no "History" option on the Tesla.com website. Below what I have in the app's loot box. Does that mean that I now have 1K miles, or is it just saying that's how much I can earn? Thanks.
