Called our office line (on the DNC Registry) said they were taking a survey. Identified themselves as "TNS", Taylor Nelson Sofres, now known as Kantor TNS, a global market research firm.  Unapologetic about calling this number even after being informed that it was a federal violation!  Although a Virginia telephone number appeared on the caller ID, she said she was calling from Lehigh, Utah.

In case you didn't know, surveys are exempt the DNC.

"If I register my number, will ALL unwanted calls stop?
No, the Do Not Call Registry prohibits sales calls. You still may receive political calls, charitable calls, debt collection calls, informational calls, and telephone survey calls."
