EWA Subscription Cancellation Request After $39 Charge

I recently subscribed to the EWA application with a 3-month recurring subscription and was charged $39 today. I do not wish to continue using this service and want my subscription to be canceled immediately. Since I will not be using the application, I kindly request a full refund of the $39 charged today and confirmation that my subscription has been stopped so that no further automatic payments are taken.

I have not yet contacted EWA customer support or the app store regarding this issue. I am submitting this complaint with the expectation that my subscription will be promptly canceled and my payment fully refunded. I request written confirmation once both the cancellation and refund processes have been completed.
