This is a user-to-user forum. No one here can refund your money. When you deleted the app you apparently did not also cancel the subscription; Apple doesn't know that you deleted the app, because what you do on your phone is private, so Apple can't cancel the subscription for you. Follow the instructions in this link to cancel the subscription-->View, change, or cancel your subscriptions - Apple Support
All sales are final, so Apple is not obligated to refund anything, but you can request a refund, and depending on the circumstances you may get a refund. Use this link-->Request a refund for an App Store or iTunes Store purchase - Apple Support
They will probably ask why you didn't ask sooner, because you get an email notification every time a subscription is about to be charged.
