Fraud. Need refund.

This is a user to user support forum. Nobody here can refund anything.

Review recent purchases at https://reportaproblem.apple.com/ or check your purchase history in iTunes and view your subscriptions. If you are the organizer of a family share check for purchases by other members.

If you cannot identify the payment then perhaps you are looking at a phishing email.

If there really have been purchases that you didn't authorize, or you've entered your Apple ID credentials at a fake Apple portal, see If you think your Apple ID has been compromised - Apple Support, change your Apple ID password, and if possible turn on Two-factor authentication for Apple ID - Apple Support.

• If there is no evidence of a charge on either your iTunes or bank/credit card accounts this is likely to be a phishing exercise which you should ignore.
  
• If there is a charge shown under your iTunes store account and it relates to misuse of your Apple ID then you need to start a conversation with iTunes Store support to get it cancelled and refunded, change your password, and enable two-factor authentication if at all possible.
  
• If it isn't connected to your own Apple ID but funds have gone from your bank or credit card account that purport to be from iTunes then the account has been compromised and you need to deal directly with your financial institution.

There is no transaction. It is a scam message.

Identify legitimate emails from the App Store or iTunes Store - Apple Support

Check your account in iTunes to see if there really was a purchase. Thousands of scam email go out every day that look somewhat look an App Store or iTunes purchase. The goal being to get you to click on a link for a refund (which does not exist in a real email from Apple). They want you to fill in your Apple ID and password on a fake website so they can use your account for various fraudulent activity.

That you see nothing under your purchases that match what the bogus email claims, then that's exactly what the email is. Bogus.

If you see any type of link that says "click for refund", "click to dispute", or any link that attempts to take you to a site where it asks for your Apple ID and password (and often lately, even your Social Security number), it's fake.

Hover your mouse over any of the links to see where it goes. It will undoubtably go nowhere near a site that belongs to Apple.
