I Couldn't find the purchase record in my account or email receipt.

Hey yutingYTC,

Welcome to Apple Support Communities. The information below may help with figuring out the charge.

One way is to look at your previous purchases. To look at your previous purchases, follow the steps below.

1. "Go to reportaproblem.apple.com.
2. Sign in with your Apple ID and password.
3. A list of your recent purchases appears. If you’re not sure what you were charged for but you know the amount of the charge, search for the amount. If you're looking for information about older purchases, find your purchase history in Settings or Account Settings on your device.

Learn what to do if you can't find the item that you’re looking for or if you find unexpected charges.

If you purchased a subscription that you no longer want, you can cancel the subscription."

You can review this information in the article: View your purchase history for the App Store, iTunes Store, and other Apple media services.

If you have multiple Apple IDs check those to see if the purchase if associated with it. Also, if others have your payment method listed used for their Apple ID, the purchase may have come from there.

If you're unable to locate the purchase, we recommend contacting Apple Support here: Get Support.

Take care.
