They were calling me first with this number : 607-739-8256

and as I could not hear the guy correctly he called back with the number on post.

I let him spoke then I told him he was hacker and he would be better to find a hionnest job, then I hand up.
He called me again, then I hang up again

An other guy just call me again said they were junior, etc... and told them to don't call again.

This is really amazing to see this kind of phone spam.

It's also funny as I have 4 computers, I repair computers, and knows a little about virus and some other stuff.

Received multiple calls from this number about my "Windows Computer," I have a Mac, and know this is a scam. He asked me if I was a certain person and when I told him I was not her, he proceeded to talk to me as if I was that person. I told him the next time he calls I will be contacting the police.

I just got a call from this number. It was a man with a heavy accent, supposedly with Microsoft. I asked to speak with his boss and told him I knew this was a scam. He admitted it and said he obviously wasn't really with microsoft.

Called from this number, told my wife it was microsoft, she did not understand, we are in the Netherlnds

It's just another scam to get your credit card.  I can't believe people fall for this, but they do. I answered one and kept him on the phone for 15 minutes, playing along, pretending to go on my computer and all that...then I just told him he was an effing liar, can't wait until the police catch you!  Added it to my block list, but they change numbers so I have to keep recycling the block list...it is stunning the amount of calls I get from this particular scam.
