"Hello, this is Carol with Interactive Security" is how the automated system announced itself. This is not a real person. I have had this number call me multiple times now. On the third call I decided to call the number back to see what would happen. I got an automated system that told me that "All representatives were busy" immediately after dialing the number and that a representative would call me within 24 hours. Then it gave some options. One option was press a number to be added to the DO NOT CALL list. When I called this number was #5.
