Steam trapped on hacked EA account - Need backend manual unbind

Hi EA Community Managers,

 My Steam account is currently trapped and linked to an old EA account that was completely compromised by a hacker. The hacker managed to bypass my notices by filtering EA emails into the trash/spam folder and successfully changed the password and primary email address.

I have completely given up on that hacked EA account and I do not want it back. However, my main Steam account is still hard-linked to that compromised EA account in the backend. 

Because of EA's platform restriction ("one Steam account per EA account lifetime"), I am completely blocked from playing any EA games on my Steam account, even if I purchase a new copy of Battlefield V.

Since I have zero access to the hacked EA account, standard self-service unlinking is impossible. I am posting here hoping a Community Manager can look into this and escalate my case to the advanced backend team to manually force-unbind/unlink my Steam account from that compromised EA account.

I am the legitimate owner of my Steam account and I can readily provide any official Steam purchase receipts, SteamID, or billing history to prove my identity.

Please help me free my Steam account so I can link it to a brand-new, secured EA account. Thank you!
