Try to Access old account/Unlink MY steam account (EA ON STEAM)

After grueling through EA support for hours, I have still received 0 SUPPORT what so ever.

I am trying to unlink my steam account from an EA account I do not have access to, nor do I have access to the email connected to it.

I have shown proof that I am who I say I am, proof that I own and currently have access to the steam account I'm trying to unlink, AND shown proof of purchase of my last EA play subscription.

Yet despite all of this, I have been denied help, cut off from an EA support chat, and now I'm shadow banned from even creating a new case so that I may contact EA help again.

I OWN BOTH ACCOUNTS I WANT TO CONNECT. I'M NOT EVEN ASKING FOR MY OTHER ACCOUNT TO BE RESET. I just want MY steam account unlinked from an EA account that is not longer accessible to me.

Please someone actually give me help ASAP.
