These callers are scammers claiming to be from Microsoft Customer Support. THEY ARE NOT! Do NOT give them info or follow the directions they are telling you to do on your computer. My caller ID showed Louisiana but when I asked them where they are from they said Miami Florida. When I asked why caller ID showed different they hung up. They have called my mom at least once a month, called me a few times as well. They are scammers trying to break into your computer to get your personal info.
