I got a call on that same day 3:39 eastern time. This must be a scam because I am pretty young and don't need their $100 dollar gift certificates or whatever.
Had a missed call, so I called it back and there was a recording saying I won 100 gift card at participating retailers. Recording said to press 1 for accept or 2 to be removed from calling list. I knew it was a scam, I bit and pressed 1, I then got connected to someone, heard muffled talking in the background, I said hello a few times then got hung up on. I called back and it said the number was disconnected.
