EA account

Hello,
I accidentally linked my Steam account to an EA account using the wrong email address — I wrote "@mai.ru" instead of "@mail.ru" (just a typo).
Now I cannot log into EA, because the email "mai.ru" does not exist, so I cannot verify or reset the password.
Please help me unlink Steam from this wrong EA account or change the email, so I can use my EA account properly.
Thank you very much for your help
