I did receive the call on 6th Feb and they said some i have won some prize money because i paid taxes on time. Infact same day i had some work near IRS office, i said i will be there in 2 hours, they hung up as well.
I have friends from Bengal, Haryana, and Andhra who have all been subject to these calls, and abused them in their native tongues saying absolutely uncouth things. Govt of India listens to so many telephone calls, cannot they nab these criminal gangs?
