You should be able to submit support tickets from within the game as well, you could open one there to get the ball rolling.
Otherwise you'll have to wait here for someone from support to see the thread and speak with you.
When you use the support section on the website there is an option for account recovery that doesn't require a log in to send a ticket. Have you tried that?

If you need to update the email address on your account, please use the account recovery page to submit a ticket so our support team can help you with this request.
