Caller type: Unknown
They say it's a survey from the State of California after the first call I ask them to remove my number and I also wasn't interested in any survey that the state of California would ever be interested in doing. They called again a week later. They know they are calling a cell phone and asks to speak to someone at least over 17 yrs. old that uses the cell phone.
Caller type: Political call
This appears to be an automated survey/robocall regarding the Affordable Healthcare Act, aka Obamacare. I did not listen to the rest of the recording as I don't care to discuss politics with total strangers (or, most likely, a computer program) but I'm guessing that I would have heard a biased viewpoint concerning the AFA.
