Not quite the same scenario, but we played a game against a team that was mostly from a specific region of India, and a couple of our players were from a different region. One of them, a bowler, had gone out to umpire and was subjected to a vast amount of verbal abuse, in Hindi. He turned around to them, warned them about their behaviour, and when it continued, walked off the pitch, for one of us to go on and (not speaking Hindi) ignore them.
At the innings swapover, their captain was informed that we weren't impressed with their behaviour and we would be reporting them to the league. Ultimately it made no difference.... They did the same thing to every other team in the league and the admin of the league did nothing.
