I bought a Buffet reward this spring which I used when I was in Vegas a few weeks later. My reward still shows as not redeemed with an expiry date of a few days from now. I'm going to Vegas next month and would love to purchase this reward again. Questions: Since the reward still shows as not redeemed, can I request them to re-instate the points back to my account (refund purchase) or would they know I used it already. Or, if I let it expire, can I purchase it again since they would think I never used it. All other rewards I purchased have properly shown as "redeemed" in my account, so I'm not sure about this one.
