The worst mobile game company. I'm level 67, but it has not happened once that I can get legendary items in the game at the lowest cost. I always have to pay a lot to get these items, while many people receive these items at the lowest cost. It never happend to me to get a gem via callback in game. This is not fair at all. I ask my friends if they have a problem similar to mine to teach fairness to this company by giving it one star rating. In my opinion, this company is a thief and a scammer
