I just got a cal from the same place, and it sure sounded like a real person. Notified the National Do Not Call folks, not that they ever do anything about these kind of calls.
Pre-recorded message made to sound like it wasn't recorded, offering us a free "I've fallen and I can't get up" type of medical alert system. This is at least the third time they have called and left the exact same message. Filed complaint with donotcall.gov.
I've turned my answering machine off - best thing I ever did!! Ringer is on really low and sometimes even off. Those in the know use my cell. I periodically check Caller ID and just giggle - LOVE wasting their time!!
