For iOS devices, please note that Apple often groups your recent purchases and sends the notification together. Sometimes they charge you later than your purchase and issue the receipt afterwards. Please check the Purchase History in the App Store or the receipts in your Apple ID email to see what you were charged for.
For Android devices, please check your Purchase History in Google Play or the receipts in your Google account email to see what you were charged for.
If this doesn’t solve the issue, please send the receipts to the Support Team. Please make sure the game name and the item you purchased are visible on the receipts.
