Cancel certificate manager service from my account

Based on your concern about unexpected charges for AWS Certificate Manager, I can help explain what might have happened and how to address it.

If you're seeing charges for Certificate Manager, you likely created an exportable public certificate (possibly with a wildcard domain) or a private certificate authority. While standard public certificates for use with AWS services are free, exportable public certificates cost $149 per wildcard name, and these charges apply immediately upon issuance.

To stop future charges:

1. Log into the AWS Management Console and open the ACM console
2. Go to "List certificates" and identify any certificates you've created
3. Select the certificate(s) you want to remove
4. Choose "Delete" to remove the certificate

Important notes:

• Unfortunately, once an exportable certificate has been issued, the initial charges cannot be reversed, even if you haven't used the certificate
• Deleting the certificate will prevent future renewal charges
• Don't confuse deleting with revoking - revocation is only needed for certificates that have been exported and is permanent and global

If you're unsure which specific certificate is causing the charges, check your AWS Billing console or Cost Explorer and filter by "Certificate Manager" under Service to see the exact details of what you're being billed for.

If you need further assistance with billing concerns, you should contact AWS Support directly through the AWS Support Center under "Account and Billing Support" to explain your situation.
