This number showed up on caller ID.  When I called back, messages says it is not a working number.  Must be spoofed?

I have rec'd several phone calls the last few days from this number. A man with a foreign accent claiming to be from Microsoft is talking. When I call the# back, a recording comes saying it's disconnected . How do you report these scammers !?

Got a call today (2-12-2016),  No name on caller id, but a live voice said 'hello - hello' several times.  Very noisy background so obviously a call from a phone bank.  Suspect either a political call or scam.  Whatever - I do not answer any call from a number I do not recognize.  And if we would unite and make this a firm practice, I believe many of these scam and nuisance calls would stop.  In fact, I think it's the only way to stop them.

I received a call from 217-844-4499 twenty minutes ago.  Caller ID said it was from Sigel, IL.  Male caller with definite foreign accent--he tried to make it sound American but failed--identified himself as James and said he was calling from Microsoft.  I interrupted him and asked him to take my number off his list.  I hung up.

I googled the number and found it was the number of the offices of a health practitioner in Sigel, IL.  Her name and address were also given.

A man that sounded like he was from India said his name was Allen, and was from Microsoft 3 times today.
