Can this be fixed?

First of all not my game. This situation was told to me. High School Varsity. Batter hit by pitch and is sent down to first. Defensive team protests need to get out of the way of the pitch etc. etc. HP umpire confers with his partner and his partener agrees he leaned into it. HP umpire brings him back to the plate. Batter get in the box and asks the HP umpire what's the count? He's told 3 and 0. Next pitch a strike and the defensive team comes out on the field to celebrate the victory. HP umpire finds out the count was 2 and 2 and not 3 and 0. Game over.

Can this be fixed or is the game over? Definitely an injustice here.
