Who called from 7172193796

Got a call from this number and the left no message. I called back and a recording answered stating that they were trying to call regarding market research and I could press 1 to be placed on their DO NOT CALL list.

This number calls my older parent but then there is no one speaking on the line! He is registered at DO NOT CALL.

Answered call and they hang up.  Do not call list is a joke.  Really irks me when they call and just hang up.

This is possibly a company that does political opinion polls/surveys and is exempt from DNC. "Exempt Organizations include charities or certain non-profit organizations, organizations engaged in political solicitations or surveys..." National Do Not Call Registry FAQ

i just want them to quit calling.
