If you're referring to purchases made with your credit card which you want a refund for, you can tap here. If you're referring to purchases you've made in-game using the Gems or Coins, this is the correct article.
Every time you make a purchase or use any currencies to upgrade an Item, you'll be prompted to tap the value once again to make sure that you validate it before spending your currencies.
We understand that, even with this, sometimes accidents happen. In cases like this, we really would like to assist you, but if we return the currencies and remove the item from your account, it will lead the game to suffer from adverse effects and your gameplay will be negatively affected.
That's why we are unable to revert an in-game purchase.
If you believe you were over charged or the item you've purchased wasn't delivered, we're here to help! Tap here to check how contact us!
