'Go' scoring with three players

A, B and C are playing.
A lays a card: B calls 'Go'; A pegs a point.
Next, B calls 'Go'. Does A peg another point?


I think you might have meant that C said the second Go. Regardless the answer is NO. You only get one point once for being closest to 31 without hitting 31 exactly. All players must say go before that person claims their point.
