Yeah I got the same call today........he just gave me Ron Jon Corporation.  Said I had registered to win a trip but got picked to receieve a discounted one instead.  
does anyone know who this is and how to stop it?

I have received 2 calls from this number. They tell me I have won a trip. When I told them I did not want the trip they started harrassing me. I had to hang up. But they keep calling my cell. How do I get them to stop calling???
