These guys call every other day at least, always in the morning and sometimes so early as to wake me up. I can hear a lot of chatter going on, but nobody ever talks to me and they hang up. They never leave a message when I let my answering machine pick up. If were just a matter of letting my machine answer  I wouldn't mind so much. But getting woken out of a sound sleep is infuriating. If I call this number, get recording that "your call cannot be completed."
