SDN/BPX survey winners

Hi, I'm a sdn/bpx survey winner, in octuber i recived a e-mail, that tell me i a winner, and they say me about my address for shiping and other general information, so until that date i don't have any prize, and i write, for a sap contact but she never answer, my name is in the list of winers inside this web site, i need to know about if i get a prize or SAP never send a Prize? is a joke??????

thanks

regards
