Since last few days my friends is getting some calls from unknown numbers which annoys him too much. He had tried to talk with the person but he does not give any proper response. Now mu friend have asked me to help him but I am too unable to come up with any such ideas which can solve his problem. Then my wife suggested for reverse cell phone number directory, but she did not know much about this tool. So anyone of you can suggest me any link for reverse cell phone number directory, through which I can solve my friend’s problem also tell me some thing about the tool.
