I am so sick of this age old scam. They say they are calling from Windows Technical Department (or try to in their best broken English). This time around, a guy saying his name was Matthew (doubtful because he could barely pronounce it)- said he was calling about my computer. I replied, no you are not, you are a scammer and what you are doing is wrong. MY GOD they get offended when you call them out like this! I'm so EFFING SICK OF BEING HARASSED.... and go ahead and try to call the number back, its not even in service. Its because telephone exchanges in the US make it all to easy for these scammers to use fake numbers to never be traced. Its time to go off the grid. Or get an air horn and for every unrecognizable number give them an ear full. This is a rather old scam that I am sure people still fall for or they wouldn't be using it still. Don't answer, or if you do just get the best of them and NEVER GIVE YOUR PERSONAL INFO OUT!
They're scammers Tom! Microsoft does not even HAVE a technical department that calls out! You can call them, but it doesn't work that way at Microsoft! These guys are scammers all the way......most likely terrorist funding. It doesn't matter, the numbers are all fake and there is nothing you can do because if you block it they will just steal another fake number!
