I received the same phone call, also in Spanish. I speak Spanish. It says "Please do not hang up. You are the winner of our monthly drawing. Press 1 if you would like to claim the prize."
Then I hung up.
I just got the call. No message. When I called back the first time it said the number is not in service. The second time I got a busy signal. I'm in the Bay Area, CA....I read the post above and this person seems to be calling all over the country. Weird.
