ETA- I deleted my post from an hour ago. Called Amex, They deposited two 30k MR referral bonuses in the final months of 2023, I recall one as it was my p2, but I have no idea who the second was, but I was able to look back and see that Amex did indeed deposit two different 30k MR rewards so I'm fine with it then. Basically, I was expecting a 30k MR 1099 and got a $600 one, so it was twice as much as I was expecting. Obviously someone signed up from my link but they usually tell me they do. My MR balance is above 100k so I didn't notice the second 30k MR referral deposited.
