So this is like a pyramid scheme then?
Ohhhh those Marketing & sales types are genius! : )

Didn't answer since I didn't know number. Did leave a voice mail. It was a recording about refinancing credit cards or loans. It was partially cut off, but that was the gist.

Called. Left no message.

These darned scammers. In Las Vegas... So we all got hit too. I shouldn't have answered the doggone phone. There wasn't nary a soul on the other end.

It appears that this if scam.  Just wanted to report it.
