Who called from 2017935561

Scammer said he was from Microsoft Headquarters....I started teasing him, chanting, " There is something wrong with your Microsoft computer" until he hung up.
Caller id said "CITCO."
This is a scam, hang up when they call.

If you have a problem with this phone number call citco 201 793-5500 this is one of their phone numbers.  If it continues then go to the police and file a complaint.

"Who is this?"

"Sam who?"
"This Is Windows Technical Support..."
