@Awakatanka You should be able to see the game on your Stadia home page. Can you scroll down a bit maybe? You should be able to see the icon to launch the game

Also you can check your order history page to make sure the transaction was successful and the game was actually purchased

@Awakatanka At this point, might be a good idea to talk to Stadia support so they can sort out your order
Go to the link below:
https://support.google.com/stadia#topic=9634925
On top right, click on 'Contact Us' > then request chat/callback to speak to a representative. Try it from a computer browser if the option is not shown on mobile
They refunded my money. That part is solved. Now i hope buying in stadia will be solved also
