A woman called from this number yesterday afternoon and wanted me to take a "quick survey"--I asked her to take my name off their calling list. She then asken me if I thought air pollution was a problem. I repeated that I wanted her to take my name off their calling list. She said "I'd be happy to take your name off of the calling list, but would you first answer my questions--do you think air pollution is a problem?" I humg up. Two hours later, a man called asking the same question and persisted when I asked him to take my name off of their calling list. I have received nine hangup phone calls from this number in the last 24 hours. These folks are bad news. Someone doing a legitimate survey would immediately agree to not call back and would certainly not call back 9 times and hang up.
