Fyber is a different entity from Quidd, with their own database, so we’re not responsible for the coins earned through their reward system.
Reach out to them directly about your missing coins by following these steps:
If you go to the Fyber Coin Offer Wall through Quidd, you can tap the "Support" icon on the top right of the page to look at a series of options. Select “Free Coins Offer Wall” and see the status of your reward. If you wish to file a report for the offers you have not received coins for, Fyber will send you an email response with a case number. Follow the instructions in that email so that Fyber can help resolve your case.
If you cannot find a resolution with Tapjoy, email us at firstname.lastname@example.org with a description of the offer and the steps you’ve taken and we’ll see what we can do to assist you.
