I lost my game progress because I was not actively playing, please don't install this game because you can be addicted to this game and want play it forever wasting your life. I have already reported customer service but I didn't get my progress back. I lost 2 more times again for other unknown reason. Just got mail to change my name in the game before my account got reset. I reported to customer service also but I didn't get it. Then I uninstalled this game. Then I installed again.
