I recently bought my panasonic home system of 5 phones and LOVE the call block. It lets you block up to 3000 numbers which rocks because somehow we are on the scammers phone lists as well.
I got the same message saying i won a cruise in Nassau in the Bahamas if i responded to 10 questions. They also mention it was a public opinion poll - which allows them to call us everyday. We need to talk to them by pressing 0 a few times until we talk to an agent (because they will want our info) then we can tell them to never call again. This is definitely a scam.
