Being associated with UNR, this has to be one of the worst possible ways to conduct a research survey. This call came to my cell. Like many others, I only pick up recognized calls to my mobile phone. And, like many others, since there was no message I treated it like a telemarketer and blocked the number. Think about it... Assuming this is a legitimate survey, and assuming the survey is aimed at some representative group or cross-section, this certainly doesn't promote accurately representative data-collection for research -- if that's even the objective. This is little more than an academic variation on the boiler-room theme, and the number will remain blocked.
Please stop calling me. I've asked nicely several time and yet you keep calling. I have stopped answering the phone when I see this number. Please stop bothering me.
