I am unable to make a purchase.

If your purchase was unsuccessful, and you received an error in the process, perform the following troubleshooting steps:

1. Check if your payment methods are working correctly, e.g. make sure your credit card is not expired and that the funds are sufficient.
2. Try using a different network connection. 
3. Restart the game. If the payment system is not initialized properly, a simple restart may solve the issue.
4. Restart your device.
5. If all of the above didn't help, please, contact in-game support service, and we'll look into your issue. Make sure to include the following information in your support ticket:
   - Description of actions that led to the error occurrence
   - Screenshots of errors which you face while trying to make a purchase
   - Whether the funds were debited from your bank account
