Unfortunately, this cannot be changed. However, we have a 5 days refund policy for SSL certificates. If you have the certificate issued within 5 days, please send a mail to email@example.com with details.
The 5 days money back period refers to Comodo, RapidSSL and GeoTrust Certificates.
SSL Certificates issued by VeriSign Certificate Authority can be revoked and refunded within 15 days after the issuance.
