The player from Russia had deposited 2000 rubles and received a bonus at an online casino. However, while he was wagering the bonus, the system had cancelled his bonus and reduced his balance from 10165 rubles to 165 rubles. The player had reported receiving unsatisfactory assistance from the casino's customer support. He had requested the return of his bonus, but the casino claimed it was a bug and returned his deposit. The player had subsequently closed his account. We had concluded that the casino's actions were justified as they had returned the player's deposit before the bonus could be wagered. The complaint was closed due to these reasons.
