Depending on your device, your purchase was handled either by Apple, Google Play, or Amazon. Since we don’t have access to your payment or billing information, you’ll need to reach out to your device’s payment platform for further assistance:
Apple (iOS players)
Sometimes, Apple combines several purchases into one lump charge, so it's possible that the charge you’re wondering about accounts for earlier purchases as well. The Coin Master Support team doesn’t have access to your billing information, so if you feel there’s been a mistake, please contact Apple Support HERE.
