repeated calls, all hours of the day or night! do not give them access to your computer, they will gain control of it. And they will charge you hundreds of dollars, to regain control.
Called at 12:20 a.m. Friday - Indian guy says he's calling from, "Window's Service Center" an 'authorized Microsoft...' I started asking him a bunch of questions about who he was, where he was calling from, company info, etc. and he hung up. Scam artist, phone thief....
Called at 4:52 am PDT -- left no message. Seems time the Feds ndand the phone companies stop cooperating with these crooks take some forthright action to stop the terrible intrusion and criminal actions of these violators.
