We are really sorry that you didn't get your credits on time, but don't worry, it is not unusual to experience a slight delay between the download and the crediting.
Just be aware that the credits can be gained for apps you download for the fist time only! Some offers require more than just the download, so carefully read the instructions.
If you have followed the instructions and still do not have your credits, please contact our partner support team by taping the "Support" button at the footer of the offerwall. You have the possibility to claim your credits two hours after the click.
In order for them to investigate your case, please also attach some proof of participation to the offer (registration email with full header, game level reached as per the required actions, payment receipt,...), your username and your Fyber ID if you have one.
Please report to us any dysfunction with their customer support.
