Hi , you charge me big amounts for Apple Music . Instead 4,99 usd per month. Please check . Ruslan

1. This is a user to user forum. You are not addressing Apple. As users like yourself we are neither charging you for anything, nor can we check what the charge was for.

2. You can view your current subscriptions by following the steps here: View, change, or cancel your subscriptions - Apple Support

and you can get a list if recent charges on your account at: https://reportaproblem.apple.com

Beyond that you can contact iTunes Billing directly by filling in this form: iTunes Store - Contact Us - Apple Support

3. What exactly was this "big amount" that was charged? How do you know it was for Apple Music?

The $4.99 price is for the Student Membership only. Unless you are a student of a participating educational institute at College level in the U.S. you cannot get that particular price. You would get the standard $9.99 individual option.
