If I purchase coins for an app and they are not credited to my account what do I do

Hello ida5722,

Thanks for asking the Apple Support Communities for help with an in-app purchase for a game. I'm happy to check this out with you. 

1. Please verify you completed the in-app purchase process correctly described in this help article: Buy additional app features with in-app purchases and subscriptions - Apple Support

"Make an in-app purchase

You have to authenticate your Apple ID to make in-app purchases. Learn how to manage your Apple ID password preferences for purchases.

2. If you have trouble making an in-app purchase, make sure that your payment information is up to date. For any other issues with in-app purchases, you can report a problem. You can also change or cancel your auto-renewing in-app subscriptions."

3. If you still can't find your in-app purchase, please check this help article next: If you don't see your in-app purchases  - Apple Support

4. If you are having trouble with you payment method, please check this article: If your payment method is declined in the App Store or iTunes Store - Apple Support

5. Lastly, this may be a problem with the network you are connected to. If you are using Wi-Fi, I recommend trying while connected to a different wireless network, or turning off Wi-Fi and trying with your cellular connection only (if possible) and check if your purchase shows up then. Be aware, this will use your cellular data until you turn Wi-Fi back on. To turn Wi-Fi off, go to Settings > Wi-Fi, and turn the slider off.

• Please make sure the other network meets these requirements: Recommended settings for Wi-Fi routers and access points - Apple Support

Thanks and have a wonderful day.
