They claim that I have won a free vacation. I told them I was not interested, and the guy said: Why would you not be interested? It's free. I know you may think it's strange because it's free, but we are running a promotion in your area.
I told them I was not interested and I did not want them calling my house again. They haven't called since.
I think they may possibly be calling from outside the US because they speak with a heavy accent.
