God bless the spammer/scammers - they keep trying the one ring hangup routine to try and trick you to calling them back - then BANG your number gets registered as a "LIVE" number and then they sell the number to other scammers/spammers/telemarketers along with also them flooding you with unwanted calls. If it rings once and you don't recognized the number, DON'T CALL THEM BACK.
Called my cell, left no message, called back and it was a automated message from "Kelly with Reward Resumptions," asking if I would like a $100 reward for popular stores like Best Buy, etc...
