I refered 6 accounts and they all show up in the log. But only 3 show up in the referral summery.
It’s possible that some of the customers you referred may have already cancelled their hosting accounts, or they signed up for products that do not generate referral rewards (e.g, they only purchased domain registrations, not web hosting). Without details, though, I can’t say for sure.
Please contact DreamHost support with details, and we’ll look into it.
