I only had one credit. I wasn't checking obsessively. I knew I had a credit because the person I recommended took delivery. The only reason I went on January 3rd was because a friend told me they used my code in the past couple months and I was checking it. At the time, on 1/3/17, it still showed the $1,000 credit. I then read the paragraph about it and saw the expiration.
No, I didn't receive an email after a referral. The only reason I know is because my friend called me and said he used my referral. He had the same Owner Advisor, who remembered me, and didn't even need my referral link. (I think he said they just looked it up and added it.)
I didn't see the expiration date on the MyTesla page until January 3rd. I had been to it to glance and see if the referrals went up from my YouTube video, but didn't read the page. (I had no reason to because I read the detailed rules carefully for the current referral program at the time.) The instant I saw the expiration, I emailed them. It's really that simple. If they claim that's enough notice, that's their decision.
I respect all the opinions here. I was mostly curious if I missed a very clear expiration notice. In searching online, I've seen others who missed it. So, it's definitely not just me.
If your friend just used your referral link in the past couple of months (as you stated above), then the $1000 referral credit that you had was not from that friend. It would've been at least 9 months to a year old. I think they've only offered prizes since last March or so (no $500 or $1000 credits for referrer since before last March).
