Fitme iPhone App Enrolls Users in Auto-Renewal Subscription Without Consent

After downloading the Fitme app onto my iPhone, I made a one-time payment for a single month. However, they automatically enrolled me in a subscription without my knowledge or consent. Today, when I checked my credit card activity, I noticed payments drawn for this month and the previous month, though I cannot see the activity from the month prior to that. Upon realizing that a total of $38 in unauthorized charges was processed over the last 3 months, I canceled my credit card.

I gave no subscription authorization for these payments, received no information regarding a subscription, and subsequently accessed no additional services. As soon as I realized the situation, I spoke with my bank, but I have not yet contacted Fitme.

I demand a full refund of all these amounts taken without my permission and the immediate cancellation of any active subscription appearing under my account. Furthermore, I request a clear, written explanation regarding this process.
