Woofz Charged $48.95 After I Canceled My Subscription

I downloaded the Woofz Dog Training app and purchased a one-week training program. I canceled the subscription immediately after making the purchase. However, afterward, another charge of $48.95 was made to my credit card without my knowledge or authorization. I am requesting a full refund for this charge, as it was made without my consent for an app and service that I did not use. I canceled my subscription and should not have been charged for a product I did not use. I request that this issue be properly investigated and resolved.
