I simply meant the referral code MUST be applied to your order BEFORE delivery. However everyone, including Tesla, says it is impossible to apply a referral code after the car is delivered. I simply asked if I could possibly check to make sure the SA did what they said they would. So, it is the old "catch 22", you can't see if the referral code was applied until delivery and after delivery it is impossible to correct. One person has suggested asking my friend to see if they had gotten the 1,000 miles in their loot box. However several comments on this site suggest they too are not given until delivery.
I'm back to trusting my Tesla SA. But, I appreciate the responses, Michael
