Why my heroes were frozen?
Mobile Legends team has noticed that recently, there were some players who tried to obtain diamonds by some bug or refunding the purchases. In order to maintain a healthy gaming environment and a fair gameplay, we will deduct all diamonds that were obtained illegally. In addition, we will freeze all bought heroes of the players who used illegal methods to get diamonds in all game modes, which means the players will no longer be able to play the Ranked Game or use their bought heroes normally. This punishment feature has been taken into effect in patch 64.0, therefore, if your diamond balance now is negative, please recharge your account as soon as possible. Thank you for your support to Mobile Legends.
