I had a similar thing happen to me. They claimed the restaurant did not participate, but asked me to scan a copy of the receipt and send it to them. I spent time doing that, and then they told me they did participate, but didn't offer rewards on that day. The website clearly shows that they did on that day. I think the program is worthless, and just isn't worth my time. It seems like they would compensate me somehow since they had me waste my time submitting a receipt, especially since I chose the restaurant in question to eat at over another only to receive rewards.
