Called at 10:08 PM. Let ring two times and then hung up when I piced up the phone. Call back landed me at an automated system that did not identify the caller, but did give me the options of "placing myself on their do not call list" (apparently the national one isn't good enough for them...) or speaking to a customer service agent (which never happened - I was just cycled back to the main menu).
Reported to the FCC. Not that it will do a lot of good.
My call was at 12:01 am. 3 rings then hung up on me. They were listed as unknown caller. I want their number to call them and wake them up! Get a real job folks!
