If the charges are not reflected in the Purchase History, then it's most likely a fraudulent charge to your credit card directly rather than an unauthorized purchase through your iTunes Store account in which case it will be up to your bank to handle. You will need to call your credit card company or bank and report the unauthorized charges. That company can contact Apple if they need additional information.
I would suggest you change your password to the iTunes Store as a precaution, but if the charge isn't reflected in the Purchase History it's unlikely that the charge came through the iTunes Store.
