Yes, as Tayay2006 said, click Claim Rewards and if that doesn't work, try Missing Diamonds by the menu for the different offers (bottom right). You can then submit a complaint to Tapjoy. They will either give you the diamonds or then send an email asking you to email them a screenshot of the app running. Then they should give you the diamonds. This has often happened to me.
