Possibly nothing. With so many people trying to get this deal, the system could just be having issues with the load.
I was lucky to get this deal on November 4th with no issues. I went in store and scanned my receipt. This is still the easiest way to use Ibotta.
You will have to wait for Ibotta Customer Support to get to your request. It is taking a week right now. Be patient. They will get to you.
Make sure you included a copy of your receipt and any screenshots with your request. To add them now, go to Account, then Help. You can view all your requests and then add comments and attachments.
Have a Happy Thanksgiving.
