Used an incorrect SWIFT code for transfer. Will money return or still go through?

I made an international transfer from my bank in Italy to the U.S. The recipient account number and routing number were correct including the address, but I mistakenly used the SWIFT code of the U.S. Century Bank instead of Italian Century Bank.

It has been 3 days now but the money has not arrived at the recipient bank. I contacted my bank but all they said was money has gone. What can I do?
