For the last three days and also earlier i am getting calls from this No. 1409740637. The caller identified himself as calling from Maruti Ltd. Calcutta office and just wanted to confirm that he was talking to me. Thereafter he conveniently disconnects and does not talk any further. this was three days back, again i get a call yesterday, and then today a female voice calls up and i threaten her not to pester me else i will complain to police to which she says sorry & hangs up. when i call up this No. i get the reply that this No. does not exist. Will some one tell whats happening?
