I was starting to get paranoid because this number calls my home, cell and work numbers. I've only picked up once, and there was no one there, or else a pre-recorded message was about to come on. Would like to call someone and complain!
I get these calls about three or four times a week, mostly around 5:00PM, but sometimes other. It seems like my voice activates some kind of computer message as quoted above. If you just answer and don't speak, there is simply dead air until you hang up.
After several months of rejection, one would think WCA would give up. But they don't. Very annoying.
