PECB holds a no-refund policy on services purchased: Certification of Persons. If a purchase is done by accident due to not carefully following instructions sent by PECB on using a Coupon Code and/or by over fulfilling the amount required, we recommend you to contact PECB at [email protected] no later than 30 days after the payment is done, so we can use it as a credit note for your future payments (maintenance fees, additional certificates, etc.).
