I got the same thing only it was a male who could barley speak english.
I told him it was none of his business and that he had called a # on the do not call list. He said they where from BFS Alarm Company???
They called at 8:15 PM - I was here but did not pickup the phone because I did not recognize the number and they were calling on a phone I use for work only. Someone said "Hello, hello" when my machine message was playing and then they did not leave any message.
