I finally had a human at the other end of the line when OTO Group called. The ID displayed as OTO Group and the phone number was 603-214-3653. I totally baffled the caller. he told me his name was Tom Johnson (I don't believe that) and the name of the group calling was actually American Diabetic Surveyor. He gave me a call back number of 1-866-290-1970. Good luck with this one!
