Orders are always intended to deliver instantly. However, delays are possible whilst the purchase is being processed. Avoid making multiple purchases by not going through the buying options again.

The first thing to do is try to restore your lost purchase by using the 'Restore Purchases' button from the in-game settings menu. If this does not help, please try the advice below.

If you didn't receive an order you made through Google after more 24 hours, please do not hesitate to reach the support service (tap on the "Contact Us" button) and attach a screenshot of your purchase receipt in your message.

To process to the in-game refund of the item(s) not received, the support service will need the Order ID which appears in your purchase receipt.
