Sometimes it takes a little more than 24 hours since the moment of payment for purchase to arrive to your game account. If after that time you still didn't receive it, please immediately contact our support team. We will do our best to help you! Make sure to provide the following information about your purchase:

1. The exact amount of the items you purchased.
2. The approximate time of your purchase.
3. If you made a purchase through Google Play: please send us GPA number of the purchase. (when the purchase was made more than 24h ago)
4. If you made a purchase through App Store: please send as a screenshot of the receipt.(when the purchase was made more than 24h ago)

The receipt is emailed to the account used to make the purchase soon after the purchase is completed. You can find more information about your purchase history in the customer support section on Apple or Google.
