I have been charged numerous amounts from iTunes why

You can use the computer and iTunes and log into your account to check to see what the purchases might be. If they are small amounts, like $1.00 and you cannot see anything in your history, it could be a debit hold, to verify your credit card. See this support document to explain that. iTunes Store charges on credit and debit card statements - Apple Support

If my first post did not help, then you can contact iTunes support. Use this link. https://www.apple.com/emea/support/itunes/contact.html

Also, this is a user to user technical support forum. Apple does not participate here, and you are not addressing them. We are users like you, and could not be sure exactly what is happening. You have been provided a place to look.
