i don’t have an itunes subscription but i get charged for it every month

Please see If you see 'apple.com/bill' on your billing statement - Apple Support which may help you to identify the item, and includes a link (near the bottom) for Support in case you still can't.

You can't have been charged without an iTunes account. It's not possible. Logging in these forums, means you have an iTunes account. As the combination of email and password used to log in here is your iTunes account.

If you want your money back, you will need to go through the links provided and request a refund. We cannot do it for you, and we cannot give you your money back. Only Apple support can give you your money back so you have to contact them by one of the methods already provided.

Follow the steps here to find and cancel any subscription you may have: link-> How to cancel a subscription from Apple - Apple Support
