Hi,

I am getting blank calls and threatening calls from multiple numbers i.e. 917503171997, 919582986335, 917417801049, 919650989967. These phone numbers are from Aircel (delhi), vodafone (Delhi), TATA - DOCOMO (UP, Uttaranchal), Airtel (Delhi) service providers. He is using abusive and bad language on calls and threatening me. I request you to take necessary actions against these numbers. Please help me in this regard.
