Billing proplem
I did not ask to subscribe to any program why you want me to pay
This is a user-to-user support forum. No one here has access to information about your billing but the following may help.
If the only indication of the charges is from an email or text, be aware that it may be a phishing attempt to get you to log in to a site that appears to be Apple and divulge your password or credit card information. See: Avoid phishing emails, fake 'virus' alerts, phony support calls, and other scams - Apple Support
and Identify legitimate emails from the App Store or iTunes Store - Apple Support
You can use the following instructions to determine if it is a real charge, what it is for, and to report a problem: Get help with an item purchased from the App Store, iTunes Store, or iBooks Store - Apple Support

If you have a recurring charge for the same amount, see: View, change, or cancel your subscriptions - Apple Support
