Upon receipt of such application and certification, the selectmen or other duly constituted authority shall, in case the tax has not been paid, issue a certificate of abatement or, in case the whole tax has been paid, draw an order upon the treasurer in favor of such applicant for the amount, without interest, that represents the service exemption.
