my steam account linked an unknown ea acc

My steam account was stolen I noticed it soon after and recovered it. But my stolen account was probably linked to an EA account from disposable emails. When I wrote to EA support they asked for the information of the account I already used I shared it with them but akash was no help at all telling me what to do he kept asking long copy and paste verification questions. The steam account belongs to me I also told them I played apex for 150 hours I did not make a purchase from EA I played the game which was free. He asked me for my IP address but he did not help because I think he wanted me to provide him with the stolen Russian email address ending in .ru and the IP address of the person who stole my account. Since my Steam account will be linked to an EA account I do not know for the rest of my life I really thank EA games support team.
