If you'd like a refund on your subscription purchase this should be done through iTunes since Apple processes and handles all subscription payments. First you'll want to login to your Apple ID and cancel the subscription. For the specific steps on how to cancel a subscription check out this article from Apple's help center. You'll also need to request a refund from Apple. Here is the link where you can contact Apple and request a refund. Follow this flow: iTunes > iTunes Store > Purchase, Billing and Redemption > Apple ID Account Billing. Finally, just make sure to add in your order/receipt number and briefly explain your issue.
