Hello @Eun Young FLIPO,
This Microsoft Q&A forum is a public community intended for discussions and general support related to Microsoft products and services. Contributors here do not have access to customer billing information, payment records, or subscription details. Therefore, we are unable to verify charges, review transactions, or process refunds on your behalf.
For subscription and billing issues related to Microsoft 365 Business Standard, please contact Microsoft Billing Support directly and provide the details of both transactions, including the invoice numbers, payment dates, and proof of payment.
- Find your Microsoft 365 admin: If you don't know who the global admin is in your organization, you can find guidance here: How can I find my Microsoft 365 admin? - Microsoft Support
- Submit a service request: The Global Administrator should create a support request with Microsoft to receive advanced technical assistance. For detailed instructions, see: Get support - Microsoft 365 admin | Microsoft Learn
If your subscription is from a partner or reseller, contact the reseller's support provider to help open a service request on behalf of you instead.
If the first payment was initially reported as rejected but later settled successfully, Microsoft Billing Support can review the transactions and determine whether a duplicate payment occurred and whether a refund is warranted.
I hope this information helps. If you still need any further assistance, please feel free to leave a comment.
