Hi Chief,

Sorry to hear about the issue with your payment. I wish I could help, but unfortunately we can’t cancel or change an order that has already been made.

When you buy gems in Clash of Clans, the Google Play Store will look at the list of Google accounts on your device and automatically charge the top-most account that has a registered payment method. In other words, if your top-most account doesn't have a registered payment method but your second account does, it will automatically charge your second account. If both your first and your second accounts have payment methods, Play Store will always try to charge your first (top-most) account.

You can change your payment methods for each Google account by accessing wallet.google.com. Also, to force the Play Store to charge a different Google account, please follow these steps:
