I have been receiving the same calls for about a year  from a group of Asian  Indians, claiming to be Microsoft tech's.  At first I just hung up. I would get the calls maybe once a month then they increased.  I now get the calls most times every day or several times a week. . I just  thought today, 3/23/17, i  would go online for the first time and putting the number on line. To my surprise there were  so many complaints that sounded just like mine.  For me there have been many phone different numbers, but this week they've been the same. I would try calling them back but I would get "SORRY THIS NUMBER IS NO LONGER IN USE", or THIS NUMBER IS NO LONGER WORKING". How do they do this? Use a number NO LONGER WORKING!!!  And why do they bother calling the same people like myself knowing I'm not falling for this scam.  When will this ever stop.  What are the officials doing about this.  Someone there has to be smart enough to figure this out.  I am 74 yrs old and can't take much more,  Lately I've been throwing the F bombs but they just sit there and take.  Please Please someone out there help these  criminals loose their voices and lock them up,
