Xbox Gamertag linked to unauthorized EA account — trapped in live chat loop.

My personal Xbox Gamertag is currently linked to a third-party/unknown EA account that does not belong to me. I have full access to my own legitimate EA account, as well as full documentation, order numbers, and email receipts proving ownership.

The issue is that whenever I attempt to resolve this through Live Chat, agents try to run verification protocols against the unauthorized EA account my Gamertag is stuck on. Because I cannot provide the stranger's private details, support marks my information as "incorrect" and closes the case.

I am not requesting access to the stranger's EA profile—I simply need my Xbox Gamertag manually released/unbound from that account so I can link it to my real EA account.

Could an EA Community Manager please escalate this case to an account specialist who can assist me privately? I can provide my case numbers, Gamertag, and proof of ownership in a private direct message.

I just wanna play skate. ☹️
