Hi, and thanks for contacting us.
I’m very sorry to hear about this issue, and want to make perfectly clear that we take incidents of this nature very seriously. We want all players to experience our games in the best conditions possible. When they inform us this has not happened, we do whatever we can to take care of it.
Like most digitally downloaded purchases, in-game currency is technically non-refundable. However, as this may have been an accidental purchase, a refund may be possible.
Because Apple serves as the soul merchant for its devices, we are not able to process any refunds on their behalf. Please contact Apple in order to complete your request.
