If you clicked on the link and entered your account id and password then change your password immediately e.g. by logging into the account via the Account > View Account (Store > View Account on older versions of iTunes) menu option on your computer's iTunes, via the 'manage your apple id' button on http://appleid.apple.com , or by tapping on it in Settings > iTunes & App Store on your phone and logging into it - after changing it you may need to log out and back into the account on any iOS devices that you have.

Where are you seeing this 'charge' ? iTunes account's purchase history ? Credit card statement ? Email ? Phishing email ? If it shows on your iTunes account's purchase history, and if nobody else has access to the account and did it, you can contact iTunes Support via http://reportaproblem.apple.com (I assume that you've already changed the account's password)

I got charge. How I get my money back? I didn't authorized this.
