Sometimes purchases take a while to process and do not get delivered immediately. You may want to restart the game to enable a fresh connection to the server.
If the items you have purchased have not arrived within 24 hours, you can contact us by submitting a request here and selecting Purchase Issue as the topic. Please be sure to add your game account identifier and attach a copy or a screenshot of your order receipt from Google Play store. The transaction ID (looks similar to this - GPA.1234-1234-1234-12345) at the bottom of the document must be visible on the screenshot.
