We need to get what we were offered and promised! It's a contract!
The issue here, I think, can be that the person which I sent a referral to used my original email address when I registered with Coinbase almost a year ago, and which I gave to her to register for Coinbase, while she didn't have any spare email for that time. So their automated system probably detected duplicate email address, which already received a referral offer a year ago. But the person who got a referral has her own name, social security, account number; it's not a duplicate profile! And referral offer was under her name!
We contacted Coinbase many times, they are not willing to help, or even to understand what the issue is and why it's not triggering the referral offer for both of us.
They should manually give me $10 and my friend $10 as stated in their referral program. We triple checked every requirements have been met on our side!
Bottom Line: No, I would not recommend this to a friend
