Unknown EA Account Connected To My Steam Account

So with the new Battlefield 6 Beta coming soon, I wanted to connect my Steam account to my EA account. When I tried to do so, it said my Steam account was already linked to an EA account with an email I did not recognize at all. My Steam account was compromised about a year ago when millions of passwords and credentials were leaked, I immediately changed my passwords and everything and removed the devices from my Steam account. I opened a case with EA, but you have to select a specific game and not just provide that it is a Steam issue, and it seems there is no way to unlink the account unless you have access to EA account (Steam is unable to do anything as it is on EAs end). Am I missing something or am I totally screwed?
