Hi,
Based on your description, your Microsoft Rewards account was suspended because of one or more of the following: multiple accounts per household or individual, being outside supported regions, providing inaccurate account info, using IP/location masking, or using automated tools like bots or macros.
Please note that here in Microsoft Q&A we are fellow users like you and do not have direct access to investigate your account. If you believe this is a mistake, the only way to appeal is to contact Microsoft Rewards support directly by filling out this form: https://rewards.bing.com/support. They are the only ones who can check your account and investigate this further.
Please note that their response time is typically 24–48 hours, but it may take longer depending on the volume of tickets they are receiving. Thank you.
