What

Received call on 14 July 2015 @ 1136A. CallerID showed " +18502903794". I let it go to recorder. No message.

Wanted to ask questions for a survey on the economy.

They called my cell phone to ask me about politics and I answered their questions but all of a sudden they hung up and when I tried to call back and gave my name it said the google subscriber was not available. Obviously a PAC or super PAC. And they really didn't care to hear all my thoughts and opinions. These type calls out of the blue to ones cell phone ought to be illegal. IMO
