I don't work for Deca (formerly Gree), so if you can't retrieve your account using the Email that is bound to the account (through the main menu in the game under "Options" and "FAQ"), and you can't retrieve it through your Game Center (iOS) or Google Play Games (Android), then you will have to contact Support for further assistance:

en-support@gree.net

You will need (at least) your Friend Code, the level of your account and the armor your main knight is currently wearing. Unfortunately not much else I can do for you otherwise.
