Certification to ISO standards is performed by external bodies.
The organization that issues the certificate is responsible for it. Complaints should be addressed to the certification body that certified the organization. You can identify the certification body by examining the statement of certification, the certification mark used by the organization, or by requesting a copy of the certificate to the ISO standard.
If the above steps cannot be followed, please send an email to [email protected] with full details of the issue and how we can contact you.
