Linked main email hacked

Hello, I was recently victim of a computer hack. The hacker took control of my main email account, so I have no control over it and no way to log in. This has caused a problem with my EA account. I have two EA games on an account other than the one I am writing to you from, and this account (with the games) is linked to my main email address and my Steam account. I want to unlink this account to the old hacked email and link it to another email address, but EA wants to send me a confirmation email to the old hacked email address, which I no longer have access to, so I am unable to change the email address linked to my EA account. In general, any changes to the account settings require confirmation after an email is sent to the old address. Is there any way I can link my EA account to another email address, given that I no longer have access to the old one currently linked to this account? Thank you very much
