Thank you for contacting iTunes Store Support. My name is Milbert your Advisor.
I understand that you would like to cancel the renewal of your In-App subscription. I can see your desire to avoid on being charged again for this in the future and get a refund. I’ll be glad to assist and provide the best advise regarding your concern.
As you have requested, I have canceled and refunded the subscription. No further charges will be posted unless you decide to subscribe again in the future.
In seven to ten business days, a credit of 11.99 USD should be posted to the credit card that appears on the receipt for that purchase.
For more information on managing your subscriptions, including how to disable the auto-renewal feature, see this article:
