Robo calling

The first time I spoke to an SSI Dynata call representative, I told him that I was not interested in discussing my political position or pain-of-view. He respectfully understood and the call ended. However, SSI Dynata is constantly calling and not leaving a message, and I suspect its to get a census on demographical positions on around the politics...perhaps tied to the upcoming elections—and this is unacceptable. Although they offer an opt out option, they do not make it accessible or easy.
