Got a call from this # only rang 3 times and I didn't answer. This is becoming really frustrating with all of these
increased calls from scam artists. DNC does not work like everything else in Washington.    

Bev apparently you didn't read Slim's post,  just above yours.   Read about the DNC.

Put the blame where it really lay's, with the criminals and illegal telemarketers.
The DNC works just fine. It is for telemarketers only and honest business does indeed abide by it. It is the criminals (which includes illegal telemarketers), frauds and scammers that do not. However, the Fed. DNC does not cover some survey's, Political or Charities.  You would need to check your states DNC laws to see if these are under your states DNC laws.  The fact remains that they are not automatic call blockers though and can not protect you from the calls that are criminal, illegal or fraudulent.

Do consider maybe getting a call blocking device or phone..  You can google them and many are around $50.00 or so.

I think it's a robo call checking to see if the number is connected. I just pickup hangup

Daily calls...sometimes two or three times a day.  Today they called themselves the "Patriot Group" and wanted to talk to the owner about our merchant processing.  I'm so sick of these calls and have told them we are NOT changing our merchant processor and to QUIT CALLING...and the very next day they'll call back again.
