Charges that I dont recognize

Hi

Go to iTunes main page bottom of page apple I'd click that view I'd Go to manage subscriptions stop the payments you don't want to pay.

When you get email bill from Apple near the bottom click on report a problem.

Are the charges from Apple or a 3rd party?

Go to settings down to Safari delete history and data.

Cheers
