Microsoft Rewards: Duplicate gift card redemption after the first order appeared as failed

I redeemed a Microsoft gift card using my Microsoft Rewards points. The first order appeared in my order error history as failed, so I believed the redemption had not gone through and submitted another order.

Later, I discovered that both orders had been approved and both amounts were credited to my Microsoft account balance. I only intended to redeem one gift card.

Unfortunately, the original failed-order record is no longer visible because the first order now appears as completed.

I have already tried contacting Microsoft Rewards Support through the support form, but I have not received a confirmation or a response yet.
Is there any way to have the duplicate redemption reviewed and potentially recover the points used for the second order? Can Microsoft Support check the internal order records to verify what happened?

I understand that Microsoft Rewards redemptions are generally final, but this was an unintended duplicate caused by the first order appearing as failed.
