Who called from 2021193763

Got a call from them saying they are microsoft tech. Saying my computer is sending error messages over the internet. Seemed like a scam so i told them I don't feel like being scammed today and hung up. Called back twice. Just blocked the number. BEWARE

Thick foreign accent telling me my computer was compromised.  Argued with me when I said I know that scam.

Same as above PC and Network Issues...except I turned the tables. I tried explaining that I didn't run windows I run Linux and then tried to sell them some big giant hairy phallus type objects but they had to use an old Wang computer running linux. She said F*C* you and hung up when she figured out what I was talking about. I hope they call again...I about peed myself.

I was not home and they did not leave a message. Caller ID said Name Not Found. I've blocked the number.

Called twice. First time I didn't answer. Second time I answered "Federal Bureau of Investigation, Special Agent Johnson". They hung up. What a shock.
