If an applicant voluntarily or involuntarily loses a position and is therefore entitled to a refund as provided in the act, such refund shall be made by the agency to the applicant within 15 days from the date on which the applicant terminated employment or the date on which the applicant notified the agency of such termination, whichever is the later of the two dates. If the agency has substantial reason to believe that the applicant has resigned to accept employment elsewhere, an additional 7 days will be allowed to complete investigations and make a refund, if refund is due.
