Hello @Shanmin Bailang
Thanks for reaching out in the Microsoft Q&A!
To resolve your situation, I recommend reaching out to Azure Billing Support directly. You can do this by creating an online support ticket through the Azure portal under the "Billing" section. When contacting support, clearly explain that you previously requested a refund, mention the outstanding charge that was paid this month, and indicate that you're currently unable to submit a new refund request. Additionally, it's helpful to familiarize yourself with Azure's refund policies to understand the eligibility criteria https://learn.microsoft.com/en-us/marketplace/refund-policies .
If you found this solution helpful, consider accepting it.
