I referred my brother and he used my code to sign up. He just made his first booking, how long will it take for me to get the $20 credit?

I gave someone my link and profile code, even though they weren't in my area. They booked with someone else and received $20 off. I received $10 for the referral and it was posted to my account after that booking was completed.

Using your promo code, your brother should have received the credit. That doesn't mean you will receive $20
