I've been receiving calls from this number as well. Normally they hang up before I answer. Today I spoke with the person and they stated exactly what you said. Though I insisted that I did not complete any survey, he persistently stated that he "just need to verify your information." When I asked him to explain what survey I completed, he hung up. I am not sure of the purpose of calling people and lying about filling out a survey or verifying people info, but it is not that important to them, that's why they hang up. Since I have Verizon, I just block the number.
