My EA ID got stolen

So decided to comeback to apex after not playing it for 2 years when i opened apex it asked me to register my email which was weird but i didn't just to find my account is back to level 1 (ive been playing since apex released) and i linked my email to my steam account  still level 1 account, I contact support and find out that my original EA ID had been transferred to a different email and that he had been playing with my apex for that entire time that, so i get support to give me back my old EA ID to my email and the new EA ID to the hacker email but my problem now is my steam account is stuck linked to the new EAID which is tied to the hackers email i asked support to unlink it but they said there is a 6month cooldown i kept asking them to escalate the ticket to the appropriate team so that this problem can be resolved but they just kept telling that was not possible.
 as i don't know what the hacker can do with my steam account linked to his EAID and im hoping posting on this forum can cause i cant imagine just sitting around for 6 months while my steam account is linked to some hacker also i cant play apex since its requesting verification  from the hackers email.
i just hope my account hasn't been used for hacking or other bannable offenses.
