They didn't bother to leave a message, which to me says they knew they had no reason to call me that I would be pleased about. If someone thinks you want to hear what they have to say, I'd think they'd say it to your voicemail...

This just gets tiresome.  And the worst part is, there's not a thing I can do about it.  Yes, I received a call from 320-300-4921.  I did not recognize the number, the caller ID read "UNAVAILABLE," so, I hit the BLOCK button on my call blocker and now it's blocked.  In fact, I just programmed by call blocker to block all numbers from 320 area code.  I get half-a dozen of these calls a day . . . IRS scam; you have won a free trip to the Bahamas; political fund-raising; you have won a free knee brace.  Do Not Call List is useless.  I purchased two call blockers . . . have both of them installed on my phone line.  I just hit the BLOCK button and it's blocked forever, still, I wish it would just stop.

this number calls me every day and never leaves a message

Call, no msg. Blocked area code. One of 13 spam/no msg calls TODAY, all now blocked from various area codes/#'s. Can't believe 13 in one day! Must be a new set of spammers, or new set of numbers to call. We don't answer if we don't know who's calling. So tired of having to constantly block #'s, but we will keep blocking area codes & numbers.
