From the moment receipts are scanned until they are processed, there is a processing timeframe. That's why your submission will be in a PENDING state during that period.
Don't worry, as soon as your request is processed, you'll receive an email informing you of the resolution, and your reward will be added to your Cashback Sock.
Is it taking longer than usual? In that case, please contact our customer support team so they can review your case
