I suspect someone used my phone to use the Apple Pay, but I did not authorize this.

Hi temecca,

We see you have an unauthorized charge from Apple Pay on your device.

You can check your latest transactions in the Wallet app on your iPhone. From there, you can see the transaction history used with Apple Pay for your debit or credit cards on file as well as your Apple Cash account.

After identifying the charge, if you'd like to cancel or dispute the payment, you may be able to do so via the Messages app. Take a look at the "How to cancel or dispute a payment" section of the following article:

• Send and receive money with Apple Pay

If you're unable to dispute the charge or locate the payment, contact Apple Support for additional assistance.

• Get Support

Take care.
