I believe this is a number from an ophthalmological magazine service. Have asked them numerous times to take me off their list, but now instead of a person being on the other line it just clicks and then turns into a fast busy. Calls about twice a day.
robo call on 9/24/12 at 1:27pm. Wasn't here to get call, and there was no message. This is my 4th robocall of the day from two different numbers. The other is a fax machine. Very annoying.
