A program that grants points for using Bing search, which users can redeem for gift cards, sweepstakes entries, or charitable donations.
Hello,
Microsoft Rewards points used for sweepstakes entries are generally non-refundable, as all redemptions are considered final. You can, however, submit a support request to the Microsoft Rewards team to explain your situation, especially if the points were used without your permission or due to a technical error.
In this case, you may submit a ticket via https://rewards.bing.com/support for this to get checked internally by the rewards team. Response times may vary due to workload or other tasks at hand, but rest assured that they will review your case and let you know on the outcome.
Hope this helps,
JC
