I received a call from 405-437-3068, OKC, I said hello twice and they hung up without saying anything. when I searched for information on this number is said it did not exist?

Another recording: this one for a "pre-paid" security alert system. But wait there's more - if you respond to this offer we have $3000 in food credits from your favorite food store.  Press "1" to set up delivery of your free personal security system.  Press "5" to decline the offer.  I hung up without responding.  Caller ID read "Oklahoma City".  

More spamming jerks.
