Sunil Bharti Mittal, Chairperson of Bharti Enterprises, at the NDTV World Summit, said a senior finance executive in the company in Dubai got a call in his voice, and tone, directing a money transfer. The executive immediately realized that I could call anyone to make that transfer...but when I heard that call recording, I was stunned because it was perfectly done and anybody who would not have been vigilant would have done something.
