I got a fraud call from a person claiming to be from "All India ATM service" and asking me my ATM card no and CVV. I had automatic call recording enabled, so I decided to play with him for a little bit and then disconnect the call. Can I go ahead and report the no. to Police along with the call recording as proof? Is it legal? I know recording calls is illegal in India and it might backfire on me itself. But what in the case of fraudulent calls?
