I think some bady tracking my phone I need help APPLE

We are fellow users here on these forums, you're not talking to iTunes Support nor Apple.

The only somebody can potentially track you is if you have Find My iPhone enabled on your phone and you have given somebody else your iTunes account id and password so that they can sign in to icloud. If you've done that then change your account's password e.g. by tapping on your id in Settings > iTunes & App Store on your phone, via the Store > View Account menu option on your computer's iTunes or via http://appleid.apple.com
