You will receive a receipt in the e-mail you provide during the check-out.
First of all, re-login to the game and wait for a few minutes.
If after some time you still can't see your purchase, please contact the Support Team.
The refund can only be accepted if there are any technical issues.
For example, if your credit card was charged twice for the same transaction.
If that happens, please contact the Support Team.
