Unexpected Claude Foundry Marketplace SaaS charges not covered by Azure credits—unable to reach Azure Billing Support

Question

I recently opened an Azure account with developer credits and deployed several models through Microsoft Foundry for use in VS Code.

On July 26, 2026, I deployed Claude Opus 4.8 and Claude Opus 5 from the Foundry model catalog. I did not understand that deploying each Claude model would create a separate recurring Marketplace SaaS subscription billed “Upfront,” or that these subscriptions might not be covered by my Azure credits.

My current billing information shows:

• Azure credits originally available: CA$283.99
• Azure credits remaining: CA$275.03
• Foundry Models cost: CA$8.96
• SaaS cost associated with the Claude plans: CA$365.94
• Current amount due: CA$0.00

The credit arithmetic indicates that the CA$8.96 Foundry Models usage was deducted from my credits:

CA$283.99 − CA$8.96 = CA$275.03

However, the CA$365.94 SaaS cost did not reduce my Azure credit balance. A personal payment method is attached to the billing profile, so I am concerned that the SaaS amount may be invoiced to it.

I discovered this issue and first attempted to report it to Microsoft Support on July 28, 2026, at approximately 6:05 PM, two days after deployment. No Azure billing case was created despite repeated portal, telephone, and chat attempts.

I have stopped using the Claude deployments and am turning recurring billing off for both subscriptions. I am seeking clarification about whether the SaaS amount will be charged, and I want to request a refund or have the amount applied against my available Azure credits if possible.

I have already attempted the following:

1. Azure’s self-service refund flow, but the transactions could not be selected.
2. The Azure billing-support request flow multiple times, but it repeatedly returned me to recommended articles without allowing me to submit a case.
3. Commercial Support telephone numbers provided by Microsoft Support, but the automated system disconnected or redirected me to the same help pages.
4. Microsoft web chat, where the agent confirmed this required Azure Commercial Billing but said they could not create a case, provide a case number, review the charges, or transfer me to a billing specialist.
5. I explicitly explained that the portal and telephone support paths were nonfunctional, but the chat was closed without resolving or escalating the issue.

Could an Azure moderator please explain how I can open a real Azure Commercial Billing case, or help escalate this to a billing specialist?

I specifically need:

• Written confirmation of whether these Claude Marketplace SaaS costs are eligible for Azure credits or will be charged to my payment method.
  • Confirmation that recurring billing is disabled for both subscriptions and that no additional charges will accrue.
    • Confirmation of whether any invoice or card charge has already been generated.
      • A review for a refund or billing adjustment because I did not understand that deploying the models created separate upfront Marketplace subscriptions outside my Azure credits.
      I can provide subscription IDs, screenshots, billing details, and timestamped support transcripts privately to an authorized Microsoft representative. I have intentionally omitted private account, payment, tenant, and subscription information from this public post.

Update from question author — corrected CCU evidence

Thank you for responding. I have since obtained more detailed Cost Management data that corrects one part of my original description.
My Azure subscription offer is a usage-based Microsoft Azure Plan. It is not Azure for Students, Visual Studio Subscriber, or Microsoft for Startups.

The Claude charges are not fixed upfront purchase fees. Cost details show:

• Meter: claude-consumption-units
• Charge type: Usage
• Purchase amount: CA$0.00
• Total Claude CCU usage now reported: approximately CA$450.44
• Non-Claude Foundry usage: CA$8.96, which reconciles exactly against my Azure credit balance

Microsoft’s documentation indicates Claude CCU is pay-as-you-go, metered hourly and reported in arrears. The portal warns that usage can take 24 hours or more to appear, which explains why the Claude total continued rising after I deleted the deployments.

I have now:

• Deleted all Claude deployments
• Disabled renewal for the Claude subscriptions
• Confirmed that the Claude subscriptions no longer appear in my active billing-subscription CSV
• Preserved Cost Analysis exports, invoices and support transcripts

My finalized invoices currently show CA$0.00 / No payment needed, but Cost Analysis shows approximately CA$450.44 in Claude usage that did not reduce my Azure credits.

The unresolved problem is that I still cannot create an Azure Commercial Billing case. The portal loops back to support articles, the self-service refund transactions cannot be selected, the supplied telephone numbers disconnect or redirect to the same portal, and consumer support confirmed they could not create or transfer a billing case.

Could a Microsoft moderator please escalate this internally or provide a functioning method to obtain an Azure Commercial Billing case number?

I can provide all subscription identifiers, billing exports and timestamped evidence privately to an authorized Microsoft representative.

Hello @dev0x

Thanks for providing such a detailed breakdown of what happened. Based on your description, there are a couple of important points:

1. Azure credits and Azure Marketplace SaaS offers are billed differently. While the consumption of Foundation Models (for example, model inference) may be eligible to consume Azure credits depending on your subscription, Marketplace SaaS subscriptions (such as third-party offerings billed with an Upfront or recurring SaaS plan) are generally not covered by Azure credits and are billed separately to the payment method associated with your billing account.
2. Since you've already disabled recurring billing, no new billing cycles should occur. However, any charges incurred before cancellation may still be invoiced according to the Marketplace publisher's billing terms.
3. Regarding the refund request, the Microsoft Q&A community cannot review or adjust billing charges. This requires the Azure Commercial Billing team. If the self-service support flow isn't allowing you to create a billing case, a Microsoft moderator can help route the issue internally or advise on the appropriate escalation path.

To help Microsoft investigate, it would also be useful to provide:

• The Marketplace offer name (or Publisher ID).
• The Subscription ID (do not post it publicly).
• Whether the subscription is Azure for Students, Visual Studio Subscriber, Microsoft for Startups, Pay-As-You-Go, or another offer.

Hopefully, a Microsoft moderator can assist with escalating your billing request if the normal support channels aren't allowing you to create a Commercial Billing case.
