This never calls after 9 pm on a week night and wakes my kids, at 6 pm (dinner time) on a Saturday, sometimes responds to my "Hello", sometimes doesn't. This is nuts!

Oops.. "Caller" not "never"

They said they were a Microsoft Partner.  When I pressed them on what that means, they hung up.  They have called twice today.

I did and im positive thats where this scumbag got my number

The individual at this number kept calling me every 2-4 days not long after I got my new laptop.  Claimed he was from Microsoft and it was in regards to my computer.  I contacted my retailer who warned me they get a lot of people calling about this, this person is a scammer.  When I told this person to stop calling me, he said "not gonna happen" in a threatening tone.  Verizon was totally useless in helping me block this caller.  I reported it to my local police and at least they will try to track this person. down.  I went out and got new Panasonic phones with call blocker built in and this number is now blocked.
