<prompt> Human: My brother was transferring me 120 so I could order something for him. I accidentally gave him the wrong last 4 digits of my account number. What do we do now? Whats the chances of getting it back? 120 isnt much in the scheme of things but still want it back. Hes with ANZ in Australia and im with NAB  <response>: He didnt accidentally transfer 400k, right? :He should call his bank and let them know it was an error. Theyll follow up or else tell him what to do. Decent chance it wasnt a valid account number and will bounce in a few days anyway. But he should be proactive.
