Numerous calls over several days from this number. Caller ID says NAME NOT FOUND and number says 844-804-1295. I answered and all they said was, Is Robert there? I asked who I could tell him was calling and they said, Hart Research, and we are doing an opinion poll. I told them we are no longer accepting these types of calls and to please remove our number from their calling list. They became rude and said they could only do that if Robert told them to.I insisted they remove our number and was told they would have to check with a supervisor. Then I was told again that I could not mke that request, but that Robert specifically would have to make that request. I repeated firmly they need to remove our number and hung up. I then called their number (844-804-1295) and got their automated number removal message, which is quite a lengthy process, and which states they are in compliance with the National Do Not Call Registry guidlines, and then asking to press 1 to have my number removed, which after doing so was followed with an almost lecture type of comment that by removing our number we would not be participating in numerous decisions were made which can affect us and other citizens .blah, blah, blah (I really do not remember what all it said), and then had to press yet another number to confirm that I wanted my number removed. I am certain they do this lengthy and somewhat pushy routine so that people will hang up before they confirm the removal has been requested.
