I’ve been charged for something I don’t know about

Hi rozan272,

welcome to the Apple (user-to-user) Community.

Re: "I’ve been charged for something I don’t know about"

Apple Support have an article online (link below) that may help:

How to see what you were charged for:

If you see "apple.com/bill" on your billing statement – Apple Support

And

If you are charged for a subscription you do not want: 

you would need to cancel that, so you aren't charged regularly.

If you want to cancel a subscription from Apple – Apple Support

If needed: 

And if the money has been deducted (not pending):

How to: Request a refund for apps or content that you bought from Apple – Apple Support

All the best :-
