Unable to merge AWS Certification accounts after losing access to source email

Hello AWS community,

I am looking for guidance regarding an issue with merging AWS Certification accounts. I previously earned AWS certifications using an email account associated with an employer. After leaving that organization, the email account linked to the certification profile was deactivated and I no longer have access to it.

I created a new AWS Training and Certification account using a personal email address and attempted to use the self-service account merge option. However, the merge process requires verification through the source email account, which is no longer accessible.

Because of this, the automated merge process cannot be completed. I have already opened several support requests with AWS Training and Certification support, requesting manual assistance. However, the responses I receive appear to be automated instructions pointing back to the self-service merge process. Additionally, when I reply to the case emails in an attempt to continue the conversation with support, the system responds, indicating that the case cannot be found or asks me to submit a new request again through the support form. This results in the issue looping through automated responses without reaching a support engineer.

Since the original email account is permanently inaccessible, I believe this situation requires manual intervention by the AWS Certification operations team. Has anyone experienced a similar situation where a certification account needed to be merged after losing access to the original email account? If so, what is the recommended way to escalate this so that the request can reach the appropriate support team?

Thank you for any guidance.
