Wondering how these numbers got my cell #.. this one called me while I was at work on my cell just now (8:30 am PT) leaves no message. I hate this crap. If you have a droid phone you can download a free app "easy filter" that you can enter the phone number you want blocked (or save from call log) and they will never call again. Hope that helps cuz the "do not call" list approach certainly never does.
