Are you sure your friend has been listed as referred by you? I don't know if you can check names (probably not due to privacy laws etc.).
If you did bring him to the game, and you didn't get your share of TP, submit a ticket to account support. They should be able to fix this for you (but you might have to wait up to 2 weeks for an answer and you need to reply to the automated email after submitting the ticket). Calling is another option if you live in the states or don't mind paying the fees.
