pls help me take my acc back

I'm reaching out in desperation because I've lost access to my EA account that was previously linked to my Steam account. I buy SWB2, 2042, BF1,etc...  but recently when I launched the game via Steam, it either asked me to create a new EA account or logged me into a different one.

I believe my EA account may have been linked incorrectly or compromised. I’ve tried recovering it through EA Help, but I haven’t had much success so far.

Here’s what I can share:

• My Steam username: Lancet
• The email I think was used for EA: mailto:[edit: email address removed] (link to my acc fr steam)

I would really appreciate any advice from the community or EA staff on how to unlink the wrong EA account or recover my original one. I just want to get back to playing without losing all my progress.
