Unfortunately we cannot change e-mail addresses on accounts as they're tied to Google & Facebook identities.
If you no longer have access to your account we can disable it and you *may* will be allowed to create a new one, based on the situation, but we will not transfer XP between them. This process may trigger additional account verification.
