I was brave and decided to call them back.  They called me on my business cell phone, so I had to make sure it wasn't a customer.  It was Star Vacation Clubs offering me a free trip to somewhere or other.  No live person on the other end, just a recording.

I too, got that message on my machine. Supposedly I won a trip.
I don't believe it, but I will call.

What the hell?
I HATE telemarketers, I didn't register, how did they get my number?
I want to know who do I have to punch in order for the calls to stop.

i just got the same call, not going to call back will probably bill my phone $3000.

[***] called me on my cell. have NO IDEA how they could get that number.

oh well, "free trip to vegas" (my [***])
