End a call like that in one move, and know the order to ring people in if it has already happened.
These four cover almost every version of this, on the telephone, on a screen, and at the door.
Key points
Put the telephone down mid-sentence without owing anybody an explanation
Name your bank’s own number and the FTC at ReportFraud.ftc.gov, and know real help has a street address
Call the bank, then the FTC, in that order, if money has already moved
What to remember
The moment worth rehearsing is the first one: putting the telephone down while somebody is still talking.
Put the telephone down first. Everything else — checking, ringing back, reporting — is easier once you are off the line.
Try this
Say this out loud once, so it is there when you need it: "I am going to put the phone down and call back on the number I have." Rehearsed once in your own kitchen, it comes out steadily on the night it matters.
