Hi,
Please note that here in the Microsoft Q&A forum, we are fellow users and do not have access to accounts. I understand that you have already read the Microsoft Services Agreement and believe that you did not violate any policy.
The only way to appeal is to contact Microsoft Rewards support directly by filling out this form. https://rewards.bing.com/support
Fill out the form completely and ensure that you provide all necessary information about your account in a single submission to help them better understand the issue.
Please note that their response time is typically 24 hours, but it may take longer depending on the volume of tickets they are receiving. Thank you.
