Thank you for this info. Just blocked this number

Scammer claiming to be Windows Service Desk. Similar call recently attacked my Pastors computer. He let them into computer without knowing. I told guy I don't have a Windows computer and slammed the phone. DO NOT FALL FOR THESE GUYS. THEY ARE CROOKS AND ONLY WANT ACCESS TO YOUR COMPUTER AND PASSWORDS. THERE IS NOTHING AT ALL WRONG WITH YOUR COMPUTER. THEY ARE LYING.

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

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

Yep Yep,

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