I too get missed calls from this number and I have made a complaint to my BSNL service provider. I traced this country code in the net and it happens to Sao Tome and Principe a small African country. I don't know who are they. I think the above two post are from mobile users living in chennai. I think they took our numbers from Facebook. Do both of you have a facebook account. Anyhow we have to be careful because I think those calls seems to be Fraudulent.
i am also getting missed calls from this number. after i pickup, i hear some mumbled tone and some background noise but nothing else. don't have any clue as to origination and whether its a fraudulent call. hope it stops.
