Received a call from 219-432-6996. No message left.

This number called me while I was on the other line and I couldn't answer. No message was left comma every time I call it is busy.

Where about do you live? I'm in Mi

Got a call from some guy at this number saying he is from "Microsoft Windows in Seattle" and needs to help my get infected files of of my computer, which happens to be a Mac by the way.  I told him he was full of $hit and he hung up on me.
