Who called from 2136291731

Received a call from"John" stating he was a computer tech. I asked him to repeat himself and still did not get the company name. He had my first name and asked if I was the main user of the computer.
That is as far as he got. I told him to take me off his list...don't call again...etc and I hung up.

I am not sure how/where he got my name since the phone is not listed with my name.

This number called thru to me unsure what they wanted but I don't know the number. Pretty sure it's a telemarketer

Getting a call 2-3 times a day. No one ever answers, just clicks, and hangs up. From Alberta Canada

This is a scammer which claims to be a microsoft tech ,only info i could find so far is from los angles cali from hill street towers at 4th and hill, microsoft techs do not call you, my advice is to hang up

Am getting very fed up with this, STOP IT IF YOU CAN.
