Sometimes it takes a few minutes for coins to be "earned". If after a couple of minutes you don't see your coins appear, then we're sorry to see that you are having problems with the offers in our app!
 
The coins are provided by a company called Tapjoy and they have a Support system in place for cases like this. Their staff is more than happy to investigate any issues pertaining to these advertisements. The easiest way for you to get a hold of Tapjoy is through the support links which they provide in each of their platforms. If you are using the in-app version of the Marketplace, you can reach them through the “Missing Coins?” link at the bottom of their list of offers. If you are going through Tapjoy.com, please go to the “Help” link at the top-right corner of the page. From there, the “Contact Customer Support” button will allow you to submit your issue. No matter the route, your issue will get to their Support team who will respond to you as quickly as they are able.
