The Caller ID showed Delivery Notice, did not answer it. Its beyond me as to why or how these idiots get my phone number when it isn't listed. Really tired of the calls; DNC seems to be utterly useless.
I've come home to this "Delivery Notice" and number on my caller ID every day this week. Additionally, they stay on the line long enough my answering machine picks up and records silence. It's extremely irritating.
