If money has moved, call your bank first. Use the number on your card or in your banking app, and say you have been scammed. Speed matters more than anything else, and the bank can act in ways a report cannot.
Then report it, even if no money was lost. Reports are how the authorities see a scam spreading.
United States: ReportFraud.ftc.gov, and ic3.gov for anything that happened online.

Have ready the message, the sender's number or address, and any payment details.
