Called and hung up after 3 rings.

doesn't speak very good English, says he is from Windows, calling about my computer, when he ask personal questions, I hang up. He sounds like a nut!

Man called (sounded to be of Indian descent).  Said he was with Windows and was calling about my computer.  I said "No, you're not, this is a scam.  Don't call here again."  He then proceeded to all me an IDIOT! and hung up.

Got the same call.  Told them I don't own a computer.  First guy told me to "kiss my [***]". I said excuse me, he repeated same and then called me a [***].
Next guy called me a liar, told him he was a scammer and I hung up.
Caller id said Compass Inc.

Got the same call. FYI, If you know Telecom you can program your phone to say almost anything on an outgoing call, It's the incoming true number that allow you to recieve calls, so the Incoming call to you may not be where the caller was calling from, this makes it hard to track. So Please question calls like this and never give out person information on calls you are not expecting!!!!
