Yes, I too got this annoying call.  I supposedly won a 2 day bahama.  I pressed 3 to opt out.  After pressing 3 a computer generated message repeated my number with a preceeding 1...long distance (?).  I traced the number to:  AMB AFCO CARGO, LLC 1013 CENTRE RD DOVER, DE 19901

I, along with apparent many others, received a call from this number. Didn't answer the call and they left no msg. Must be something that can be done to EFFECTIVELY remove my CELL phone number other than the infamous do-not-call list, which is a JOKE!!

I received a call from this number on my cell on 8/10/11.  It is definitely a Delaware number.  The person on the line claimed he was from an outfit called SOS.  I am on the Nationwide Do Not Call list and don't understand why these people continue to call.  I have nothing to do with them, businesswise or otherwise.  I find it difficult to get them to stop.  It sounds like a robo-call.
