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 via the 'No' option below, or email: firstname.lastname@example.org
