Wanna-be-Microsoft scammer/s.
They call every other day via different phone numbers.
Tell them you use Apple...Even though they will continue calling.

Just now my caller ID showed (202) 119-3763 'caller unknown'.  As usual I do not answer BUT READ ON PEOPLE... I usually hit *60 (Xfinity Voice) so I can add the number to my blocked calls.  This service repeats the REAL number that called you to confirm if you really want to block it.  So when I hit # to add the last call received, imagine my surprise when the auto systems IDs the last number as 849-127-8459.  849 area code is of the Dominic Republic.  I plugged that number into this site and read all the fun stuff there, too.  They're hiding their number, but you can unveil it with a blocking service that only recognizes the true incoming number, not the number and name showing up on your caller ID.  Try it!

Caller ID reads: NAME NOT FOUND

Lady with this number called.  She claims to be Windows Support Tech.  (From other related calls, I will assume she was going to say my computer has been sending them error messages.). She asked if my primary computer was on and if I was near it.  I said my primary computer is Apple.  She hanged up.  Her accent was of India.  Caller ID says unknown caller.

I got a call from these guys and blocked it.

On another topic,  I've been plagued with at least a half dozen calls labeled as PPP, or maybe "private number".  There was no way I could block it so the calls kept coming.  Finally I answered and it was the "Leukemia Society".  The lady seemed to be very nice but I was interrupted in the middle of some work I was doing outside and I was very agitated,  I told her I will never donate to them given the fact they use a hidden- unblockable -  phone number.  After a couple F-bombs,  I hung up.  I'm spreading the word as best I can to you guys......
