apple charging me and I have no idea why

Where are you seeing this charge?

If its just an email saying you were charged, make sure its actually from Apple: Identify legitimate emails from the App Store or iTunes Store - Apple Support

Have you verified your purchase history: See your purchase history for the App Store or iTunes Store - Apple Support

Your subscriptions: See or cancel your subscriptions - Apple Support

If the charge is not there, and you only received an email, then its very likely a scam.

We are not apple, this is a user to user community.
