missing dell rewards

Hi,

Yesterday, I was going to place an order and use my reward points. However, during the checkout process, I received an error message saying, "Check your reward points." When I checked my account, I saw that my reward points had dropped to 0. I had 52263 points in my account.

In the reward history, it shows that I redeemed the points on December 26, 2025 — but I did not redeem any of my points, and I didn't make any purchase. The expiration date is 2026, so they should not be expired.

How I can get my reward points back? What is the issue here?
