EA Account Hacked - Verification Code Sent to a Strange Email Address

Update & Major Obstacle:

Unfortunately, I have hit a dead end with the official process. I tried to submit a case through the EA Help website, but the system would not allow me to submit the case/report at all. It seems I am completely blocked from using the normal support channel to inform an actual EA staff member about my situation.

The webpage runs smoothly without any network issues. After pressing the submit button, there is no response and the case cannot be submitted at all
