Find out which account is linked to Steam currently

Hey guys, i logged into SWTOR after downloading it on steam and it linked my account.
Problem is i cant remember which username i made it with and im unsure which is linked.
My main account says it is not linked and will not work, but every other one ive tried seems to not work either.
Is there any way i can just find out which Username is linked to my Steam currently?
Tried calling support and got hung up on after 20 minutes so this is my last ditch. Kinda mad cause i paid $30 for a subscription and now i cant access it.
