I'm not sure if my purchase has been added to my game or not

No need to worry, we can help you with this issue. Here are the steps you should follow:

- Close your game and reopen it, and then check your in game currency balance. Chances are there has been a delay in the system and your currency is now added. If not, move onto the second step.
- Copy your GPA number if you've made your purchase on Google Play (android) or your Transaction number if you've made your purchase on App Store (Apple/iOS).
- On your in game settings menu, tap the Support button and then the "Send a Ticket" button.
- Explain the situation and paste your GPA or Transaction number.
- Hit send. An agent will help you with the issue further as soon as possible.
