If you are on a do not call list, they can not call you period. Whether they show up on caller ID or not is irrelevant. IF you are on a do not call list, go to donotcall.gov and register a complaint
According to caller ID the call was made on 8/18 at 9:19 am. I was out at the time, and they did not take advantage of the fact that I have an answering machine.
Got a call at 1:37 PM. Left no message on my answering machine. But you know, as long as they display their number, I am not sure they are in violation of the do not call list. I may be wrong about that, however. But I am on the do not call.gov list.
