A con artist will contact you and tell you he is a bank official and that he needs your help to catch a dishonest bank teller. All you have to do is withdraw your savings and give the money to him so he can check the serial numbers. If you do, you've been "stung".
A real bank official would never ask you to withdraw your money. Is it hard to believe that people fall for such tricks? Con artists may be the greatest actors you'll ever meet. The pigeon drop and the bank examiner schemes are two of the most successful con games around. Don't be fooled.
Call their bluff before it is too late.
