Another nuisance call from "name unknown", or maybe "unknown name".  If they don't want to disclose their name, I don't want to speak to them.  That goes for calls from "unavailable", too!  I get 5-6 of these calls every day, and I'm sick and tired of getting up to answer the phone, and, again, find a call I don't want to answer.  It has got to stop!  At least I don't get these incessant calls on my cell phone, which is a miracle!
