Monster,
Welcome to iTunes Store Customer Support. My name is Vipul.
I understand that you accidentally made a purchase for the app "MU Origin-TH". I am sure you do not want to be charged for some purchase that you dint intend to make. Not to worry, I will look into this issue and get it resolved as quickly as possible.
Monster, I’ve reviewed your case and am issuing you a full refund for the unintentional purchase.
Within ten business days, 69.99 USD should be posted to the payment method used to make the purchase.
