Do I qualify to get bonus email addresses?

Hi there. I am helping a friend who has started a small business.  She was looking for some email hosting options and I researched and recommended Zoho to her.  I set my own domain up to see how it all worked before I made the final switch for her.  Now that I have both our domains set up on your Lite plan, I am hoping that we can both get the email account bonus restrospectively applied as, in effect, I did refer her.  When I try to "invite" her, I get the message that she has already signed up.  Not a major but it would be great to have those additional email accounts.  Many thanks.
