Orders usually deliver instantly, but may take longer. When such delays occur, it means the purchase is still being processed. There is no need to try purchasing the same pack again - it should arrive soon!
If you still haven’t received a purchase made more than 24 hours ago, please contact iTunes support. All payments made toward the game are processed by Apple. You can reach them right here.
Feel free to contact us with a screenshot of the receipt for your purchase if you have any purchase-related issue.
Our apologies for the inconvenience, please let us know if there's anything more we can do for you.
