Someone called me stating that there is a requirement for the verification of my ATM card and he said he was calling from the Head office of all India banks. I asked him which bank the ATM card belonged to for which he said I had lodged a complaint as the card was blocked and the call was from the Head office of RBI connecting all the banks in India.
