Cannot unlink Steam from inaccessible EA account – need manual unlink

I need help unlinking my Steam account from an EA account I no longer have access to.

Issue:

My Steam account is linked to an old EA account. I no longer have access to the email/login, so I cannot unlink it myself.

Important:

I am NOT requesting access or recovery of that EA account.

I only need my Steam account unlinked so I can link a new EA account.

Proof:

I can fully verify ownership of my Steam account (profile, purchases, library screenshots).

Problem:

Support keeps redirecting me into EA account recovery, which is not possible since I don’t have access to the old email.

Request:

Please escalate this to someone who can manually unlink the Steam account from an inaccessible EA account.

If there is any alternative process for unlinking without EA account verification, please let me know.

Thank you.
