The refund procedure depends on where you purchased the subscription.
Subscriptions Purchased on the App Store
Everything about App Store subscriptions is entirely managed by Apple, including charging for trials, renewals, and refunds.
This may look inconvenient, but this is Apple's decision - they want to own the billing experience and don't let app developers anywhere near it. The bright side is that no dishonest app developer can ever charge, overcharge or double charge on the App Store - Apple keep its customers safe.
Please see Apple's support article iOS App Store Refunds for detailed information on getting a refund.
Please notice the Apple's refund policies vary country-by-country, see policies specific to your country. To identify your Apple ID used for the purchase of iOS App or iOS Subscription, see the related article provided by Apple.
