I got the same call today & when I responded there was a recording saying that I had just won a free to the Bahamas that all I had to do was to complete a survey. I immediately hung up knowing that this was a scam. It was a number from Los Gatos.
I just received a call name this morning 6-13-2014 10:00 am from a Thomas Raymond 408 - 356-1429 I kept saying Hello!!! They never did speak I blew a whistle in the phone thinking maybe they could hear that
