oh man this is a funny topic, and something like this just happened to me last week too.

I get a phone call from a restricted number while I got home from work. Thinking it could be something to do with work, I answered it. It was a guy with a thick Indian accent by the name of "Alex," and he was saying that my computer was not responding to Windows Updates. Considering I work with computers and stuff a living, I told him he was wrong and explained why, while he just kept talking, much like he was reading off a script. I kept explaining why he was wrong, and he hung up on me.

Later in the week when I was talking to my mom, she got the exact same call and everything! Pretty strange indeed, but she thought the Alex dude was talking about her windows at home, not like the windows computer. xD
