In the last month this number has called at least 4 times. There is music when we pick up the line. When we try to find out who it is and what it is about the caller got abusive. He started yelling and wouldn't put me through to a supervisor or give a legitimate name or address. When I returned the call the person who answered started yelling at me as soon as I asked for a supervisor. I said nothing else, I just calmly asked to speak to a supervisor and this second nutjob went off on me. Let them call back. I have nothing better to do all day long than report them to the FTC and my state's Attorney General.
