I got a call from this number on Friday afternoon.  The moron on the other end had a thick middle eastern accent and started telling me that my laptop had been compromised by somebody somewhere.  Obviously a scam attempt when he asked me if I had a computer.  Then, in his incoherent rambling he said that his " certified microsoft technician" would go into my computer and add the appropriate software to prevent any more intrusions.  Before I could get him to shut up the last words he said were "all we need is your password".....I went to insult his family heritage and hung on him....
DO NOT give these idiots any information at all.....if you do, you'll be sorry.......

Multiple calls to my child's cell phone without leaving a message. They answer with "live tech support" but you are talking to a robot.  The number may also be associated with tollfree.com.

They call. When I call back no answer just a 3 beeps and then hangs up

the call every day
