Rollic does not have the ability to process refunds for iTunes Appstore transactions since purchases made are through the iOS payment platform.

To request a refund, go to reportaproblem.apple.com.
  1. Sign in with your Apple ID and password.
  2. Tap or click "I'd like to."
  3. Choose "Request a refund."
Please wait for the payment to post or for Apple to send an email of the receipt before requesting a refund. App Store refunds typically take a day or two to process and you might get contacted by Apple Support to verify the reason for the request.
