I have an Apple Charge on my personal credit card of 64.95 that I did not authorized.

If there is a charge.

Apple ID - If you see ‘itunes.com/bill‘ or an unfamiliar charge on your bank, credit card, or debit statement.

Contact iTunes Support about not being able to log in. See the Apple Support articles below for contact information.

Then what it sounds like is someone hacked your iCloud account and have taken it over. Including changing the password, which would prevent you from logging into the App Store.

If you think your Apple ID has been compromised - Apple Support

Check to see if this is what has happened by trying to login to your iCloud account with what should be your correct ID and password.

Also, call your credit card company and have the current card cancelled to prevent any more unauthorized purchases.

Are you sure you've actually been charged anything? Open iTunes/Music and login to your list of purchases from the App Store or iTunes. If you don't see it, then the message is a scam.

These types of scam emails are rampant. Dead giveaways:

1. English and grammar reads like as if the person who wrote it just started learning English last week.
2. Return email address does not go anywhere near a domain owned by Apple.
3. Has links (usually really big buttons) to cancel the purchase or to login to your account.
4. Has any type of attachment (typical are PDF or Word docs).

Apple never, ever does any of these.

We are users like you, not Apple employees, so we don't have access to your data information, so we can't help explain what the charge was for.
