Thank you for answering.
I want to refer them, have them open an account, and then merge them into one group account the next day or so.
I hope that gives us the referral credits.
Also, would you know if they refund partial months; for example, if someone signs up for a $50 monthly plan and then ten days later merges his line into a group so his line should be $30 now, 1 - would they refund the remaining of the $50, 2 - and would the people in the group get refunded since now there's another person in the group and their lines should be less?
I hope I'm being clear.
