Who called from 2122122121

recived call from this number. didnt leave message or anything. didnt pick up.

I just got a call from that # claiming to be Gene, an engineer from Microsoft, calling about my computer. He had a very heavy accent & couldn't pronounce engineer. I told him I didn't have a computer & he hung up.

Keep getting calls but nobody says anything when I answer then when you call back not a working number how did they get my number in the first place

They call every 30 minutes.  I don't answer they don't leave a message & in 5-10 minutes they call back with a # Unknown.  I don't answer still no message.

has called me 3 times in 2 hours.  no message and isn't a working number on return calls
