In rare cases, customer's may miss these emails or forget to follow up. If, after a week, the customer still hasn't updated their payment info, their registration is considered overdue. Thankfully, CourseStorm will automatically notify you when this happens so that you can contact the customer and resolve the issue either by reminding them to update their payment information, or, if necessary, canceling their registration altogether.
