Q: itunes billed me and i have not bought anything, why am i being billed

How are you finding out that iTunes billed you? Did you receive some type of email? That may be a phishing attempt. If not that, then check out this support document about credit card holds. iTunes Store charges on credit and debit card statements - Apple Support

If it is a full charge that you are not aware of that you can see on your credit card statement, then you can go to https://reportaproblem.apple.com and notify iTunes staff. You also have the option to contact iTunes support here. http://www.apple.com/emea/support/itunes/contact.html
