another wierd situation

what is the official ruling in this situation??

flop comes TJJ, 2 people in the pot, first position bets, second raises, since most people are loudly talking, dealer thought it was just a call, and before the bettor can even call, he flips the turn. what would happen if the dealer deals the turn without EP calling the raise? would the card be mucked, or would the raise be called back?
