They called and asked for someone and rudely hung up. I called back and they wouldn't tell me who they were.

Caller ID, no message.
Call back = "The number you called is not in service."

If the number isn't in service, why did it show up on caller ID?

Oh yea... its a scam....

Don't know this caller.  Wehn called back "number not in service"  How can that be.  Our number are on the Federal "Do Not Call List"  Why did they call us?  Filed a complaint.  Hopefully that takes care of them calling again.

The DNC list does not automatically block calls.  Instead, it provides a list of  "do not call" phone numbers to legitimate telemarketers who pay a fee for the list.

The DNC list exempts political callers, survey organizations,  charities and companies with preexisting business relationships, but these organizations might have their own, internal Do Not Call list (ask them).

The DNC list  is not effective against criminals, spammers and scammers, because those people do not subscribe to the DNC list, and do not care if you are on or off that list.
Its purpose is to stop calls from legitimate telemarketers, and it does a pretty good job at that.
