If you think that you have fallen victim to wire transfer fraud, you may be able to recover your money by doing any of the following:
Quickly call your bank and ask for a reversal of your SWIFT or SEPA payment to the fraudster.
Change your password if you still have access to your account.
File a complaint with the Internet Crime Complaint Centre (IC3) of the Federal Bureau of Investigation (FBI), especially if you are in the United States.
File a police report and contact other relevant local authorities.
