The credit card bought something on the American website, but the payment failed, and the bank sent a text message about the consumption amount. What should I do?

First of all, Macy's doesn't accept credit card payments from addresses outside the United States. Most official website does not accept credit cards with addresses outside the United States.

Secondly, this situation is mainly due to the settlement between your issuing bank and foreign countries. After you place an order online, the system will place the order successfully by default, so that there will be remittance. But after that, MACY will inform your card issuer that the transaction did not happen and your card issuer will transfer your money back. Don't worry.
