First checks
Open Transactions and select the gift card order — the code, redemption link, and PIN (when the brand uses one) are shown there, and they're also in your confirmation email. Some brands deliver with a short delay while the partner confirms the order, so a "pending" code can be normal for a little while.
The code says invalid or already redeemed
Don't buy a replacement — contact support through the messenger with the order ID. We report the code to our gift-card provider for verification and share the outcome as soon as they respond; recovery usually takes a few business days because it runs through the provider's own checks.
The funds were deducted but I got no code
Same path: message support with the order ID. If the order failed on the provider's side, the amount is refunded to your reward balance.
The redemption link shows a blank page
Try an incognito window or a different browser or device — see "Fixing codes and redemption links that don't work" for the full steps.
