I have been receiving calls from the mobile number 9176856779 for the past one week. Whenever i pick the call the person on the other side uses filthy language and asks who is speaking from this side. When i tell him that it is he who has called and ask him whom he wants to speak to, he uses filthy language and also threatens me saying i know your number, now see what happens. I have also warned him stating that I will be going to lodge a complaint for such calls, for which too he threatens saying 'Now if u go to complaint, come here directly or i will come there and ruin everything'. I donot want any such disturbance, cos i donot even know who this person is. He has been disturbing, saying it is some lodge he is calling from. Please help stop this and take formal action
