How to get a refund for unused storage

Submit a new Azure Billing → Refund Request support case for the September 1–30, 2026 invoice; the August refund does not automatically refund later invoices.

Submit the September refund request

1. Sign in to the Azure portal using the account associated with Azure Subscription 1.
2. Open Help + Support → Create a support request.
3. Enter Billing, select Billing, and select Azure Subscription 1.
4. Select Create a support request at the top rather than a suggested article or automated refund option.
5. Set:
   • Issue type: Billing
   • Problem type: Refund Request or Unexpected charges
   • Problem subtype: The closest available storage/unrecognized-charge option
6. If suggested solutions appear again, select Return to support request.
7. Under Additional details, provide:
   • The September invoice number and billing period: September 1–30, 2026
   • The storage charge amount
   • The date and case number of the August refund, if available
   • A statement that the storage was unused and that the same charge recurred
   • Confirmation that the subscription has now been canceled
   • The subscription ID—do not post it publicly
8. Complete Review + create, then select Create.

Azure directs billing and refund questions to a billing support request.^1^ If the refund workflow loops back to the beginning, the supported Q&A procedure is to bypass the refund suggestion, select Create a support request, and then Return to support request when recommendations reappear.^2^

Refund approval cannot be determined in Microsoft Q&A; Azure Billing Support must inspect the invoice and account.

Attach the charge details

If the invoice is still accessible:

1. Go to Subscriptions → Azure Subscription 1 → Billing → Invoices.
2. Find the September invoice and select its download icon.
3. Download both Invoice and CSV.
4. In the CSV, filter by the storage-related MeterName, and attach or quote the relevant rows in the support request.

Alternatively, open Subscriptions → Azure Subscription 1 → Cost analysis, choose Invoice details, select the September period, and filter by the invoice number. For individual pay-as-you-go or Visual Studio subscriptions, the invoice and detailed usage file can be downloaded by an account administrator or Owner; the CSV identifies charges at meter level.^3^

“Unused” does not necessarily mean unbillable: Azure Storage charges can include stored capacity, redundancy, transactions, and data egress, even when no application is actively using the data.^4^ Ask support to identify the exact resource and meter responsible for the recurring amount.

What to expect after cancellation

Cancellation stops subscription billing immediately, but Azure can still issue a final invoice for usage incurred before cancellation. Azure closes the final billing cycle within 72 hours, and temporarily retained data after cancellation is not charged.^5^

Therefore:

• The September invoice remains a separate charge that must be disputed.
• A later final invoice does not necessarily indicate continued post-cancellation usage; check its service dates and meters.
• Keep the cancellation confirmation and any subsequent invoice for the support case.
