I have caller ID and answering machine.  Party has called  as many as four times a day. I will not answer if I don't know who it is.  That girl, you verified what I though. It is a spoofing number.  If I don't answer the phone they call back with another number in five minutes sometimes.  Today party called and just laid the phone down.  I could hear people talking in the back ground.  I just picked the phone up and hung up.

claimed to be microsoft help desk answering a report of log-on issues.  Problem is that I had not reported any issues

Yep Yep,

Thank you for this info. Just blocked this number

Three calls within an hour. I've had it with them.

Or some kind of magic jack phone numbers, They are relentless. Keeps calling every hour!
