Don't dial star 60 to block a call if you have Verizon. They charge 50 cents A DAY for a blocked call. Found out the hard way. It will cost you a fortune.
They called again today (after I told them off yesterday). When I saw "Out of Area" again today, I simply clicked "Talk," counted "one thousand one" (silently) and clicked "Off." Then I giggled! They immediately called back and I did it again...and giggled even longer. If I can't stop them, I might as well have some fun.
