First things first, please make sure you’re connecting to the right Google Play account. In lost account cases, it’s extremely important to use the correct credentials when logging in. If you can’t prompt your desired account with the email address you’re using now, that means it's probably not the right one.
To properly access your account, please:
1) Make sure you have added the correct Google Play account to your Android device
2) In the in-game settings, tap on ‘Google+ Sign-in’ and connect with the e-mail address originally used to sync your account (the one you have lost)
3) If your account was linked to an old email that you no longer have access to, contact Google Support to recover your account’s information.
AN Games cannot access information related to your Google Play account, so we need the help of both you and Google to find the correct login details that will let you recover your account.
