Hello,
Thank you for getting back to us. Unfortunately we weren’t able to verify that you are the original owner of this account, and therefore can take no further action. Once an account has passed from one player to another, we are no longer able to guarantee its security, or integrity.
To avoid future unauthorized access to your personal game account, make sure to never reveal your Game Center or Google Play account details to anyone.
Don’t forget: transferring an account from one player to another is a breach of our Terms of Services, and may lead to your account being banned.
If you have any further questions, please don’t hesitate to ask.
Very best,
