See who's calling

Indian scammers from "Bank Security"/Visa who aim to run Authorised Push Payment Fraud, where they lie and tell you there are unauthorised transactions on your debit card, they suspect somebody at your local bank branch is involved, and con you into transferring your money to a so-called "safe" bank account so they can steal it. Or they may tell you to take thousands out in cash and post it to a money mule.
