Hi olgaemir,
Thank you for using the Apple Support Communities.
It sounds like you want to report unauthorized charges and we're happy to help!
Please note that: "Apple Pay uses security features built-in to the hardware and software of your device to help protect your transactions." "Apple Pay is also designed to protect your personal information. Apple doesn’t store or have access to the original credit, debit, or prepaid card numbers that you use with Apple Pay. And when you use Apple Pay with credit, debit, or prepaid cards, Apple doesn't retain any transaction information that can be tied back to you—your transactions stay between you, the merchant or developer, and your bank or card issuer." For additional information check out the Apple Support article Apple Pay security and privacy overview.
