My steam is connect to a acc which i do not know ?

My Steam account has been linked to an EA Account that I do not own or recognize. EA shows the account as pr*****@travisbezos.com. I believe this connection was made without my authorization. My Steam account is mine and I need the unauthorized EA account association removed so I can link my legitimate EA Account and play Battlefield. Please investigate the unauthorized Steam/EA link and help me recover/remove it.
