Called twice at 6.30 am on a Saturday. When I eventually called back, there is a message, referencing the entire phone number as an "extention" and to leave a message. I did leave a message, indicating that I will do whatever is necessary to report them, track them down and sue them for harrassment! And I will! I am sick of these people. My best guess is that they are paid to find and verify phone numbers that can then be used late for some nefarious purpose!
