Anyone receive calls from this number?

Charter One

Called saying they were a publishing company, then when i asked to put me on a "do not call" list, they said they didn't have one, then when i asked them to take me off their call list they said they didn't have one. then i asked how they got my number, their response: "None of your [***] business, [***]"

they just called and said they were CPS (child protective services) from Denver, Utah.

its a michigan number though
