Long story short, when I was signing up for my SEGA ID the game wouldn't accept any of my valid personal emails, so I used a disposable email thinking it would be easy to change later on. Boy was I wrong.

Is there any way I can change my email without knowing what it is already? The only thing I found was a FAQ support page saying I could fill out a form to request a change but it said if I was overseas they wouldn't help me. If I put in a ticket anyway just to see if they will help me, will I be banned because I'm not from JP?

ps. I can still login and know my other information.

Please, please let me know if any of you can help me. I've encountered so many issues while playing because I can't remember my email.
