Depending on where you made your in-app purchases, the process for refunds is different.
Please send the Wonder Merge Support Team a message by tapping the "Contact us" button in the game settings. Make sure to attach a screenshot of the Google Play receipt that you received via email when you made the purchase. The screenshot should include the order number which starts with 'GPA'.
We would like to assist you in this matter, but due to the App Store's policies, we cannot process the refund for you. In order to get your money refunded, you have to request the refund to Apple directly.
Please visit the official Apple support page to find out more about how to get a refund for purchases with Apple.
If you have any other questions, then please CONTACT US directly!
