Received a call from this number and caller did not leave a message. I do not know anyone with this phone number.

They told me I signed up for some wal-mart thing and when I told them I didn't they rudely stated: "you're not interested in a million dollars?" and hung up.

When number pulled up shows Atlanta, GA.  Don't know anyone in Atlanta.  Does anyone out there have any idea who is calling from this number?  No answer when try to call back.  My theory is it is a "front" phone number used by scammers.
