Refunding a registrant is a simple process and starts with your merchant account. Log into your merchant account used for processing online payments and follow their instructions on refunds.
After you have processed the refund, the next step will be to make applicable edits to your registrants . In the 'Registrants' section you have the ability to delete or change registration information. Admin notes can also be applied by clicking the arrow to the left of the registrants name and editing the section labeled 'Admin Notes'.
