It can be very concerning if you see charges on your Google Play Store account which are unfamiliar to you.
It’s possible that they are valid charges and relate to purchases which you may have overlooked, so it’s important to first check your order history to see if the charges match the items you’ve bought.
To put your mind at rest, here are some steps you can take.
Check your purchase history first
Google Play will send you a confirmation email every time you make a purchase. However, if you no longer have the email receipts, you can find them listed in your order history here - just scroll down to 'Find your Receipt and Order Number'.
If the purchase is still not recognized, report it to Google Play immediately
King would never apply charges to players’ accounts without authorization and there are no hidden features or purchases in any of our games. All in-game purchases must be initiated in-game. Before a purchase is completed the buyer must also confirm the Google Play Store payment details and submit their password or give fingerprint authorization.
If the purchase has been carried out without your consent or knowledge, using methods to bypass the security of your account, you must immediately report this to Google Play. They can be contacted for issues concerning activity and fraud on your account here
Google Play will investigate this, the security of your account, and arrange any appropriate refunds for purchases carried out without your consent. You may also want to contact your bank and the police to report the fraud.
