What should I do if my mobile phone game is deducted?

There seems to be no way for this. You'd better ask the seller for a refund, but it is usually available on large websites. You can go to official website to have a look, or just look in the app Store, enter the name of the game you are looking for, and then the App Store will automatically find out a lot of similar games, and then you can sit in the right place. Compared with other downloaded apps, I like to use the App Store, mainly the games I downloaded. You won't get stuck when you play.
