A law office?

said that they were a publishing company and i was entered in a sweepstakes from visa.  Wanted my card number and other information.  Called visa and said that this was a fraud!!!!!!

called me today at 2pm. did not leave a message. i'm gonna call when I get off work and see who it is.

I got a call today too from that number at 3:37 pm.  Called them back to see who it was because they didn't leave a message, and no one picked up.  Tried again later, and again, no one picked up.  Not sure who it is, but whatever it is, it doesn't sound good.
