When an in-app purchase is made, you will receive a confirmation message and the item(s) will appear immediately in your game.
 
Before making a purchase, we recommend ensuring that your device is connected to the internet, and that you have a valid payment method associated with your iTunes account.
 
If the items don't appear immediately, something has gone wrong with your order. Please contact Apple Customer Care for further assistance: https://support.apple.com/contact
 
If you have followed these steps but still require further assistance, please contact us
