Dear Sir, I have received a call from Mobile no. +917763098761, and He told me that he is calling from ATM office, Mumbai and he called for ATM card up-gradation. He was asking private details like ATM Card Number, PIN Number, Card Type, Bank Name etc. But when I denied him to give all these details, he just cut the phone. I also have his voice recording and name. So I request you to take some action against this caller to prevent innocent people from fraud or cheating.

Regards
