How can a Microsoft for Startups user escalate unexpected Claude Marketplace billing?

I have approximately ₹9.49 lakh of Microsoft for Startups Azure credits remaining. I deployed Anthropic Claude through Microsoft Foundry and later received invoice G183537293 for ₹70,716.76 because the Claude Marketplace usage was not covered by the sponsorship credits.

I understand the eligibility rule now. My question is about escalation.

Azure Billing has told me Marketplace adjustments are handled by the publisher. Anthropic has told me Azure Marketplace billing is processed through Microsoft. I have therefore been redirected between both parties.

I also found a previous Microsoft for Startups case involving similar unintended Claude/Foundry usage where the customer reported receiving a $1,000 special-exception credit:

Is there a Microsoft for Startups, Marketplace billing, or Foundry escalation team authorized to review a one-time goodwill credit in this situation?

I am specifically looking for the correct escalation path, not asking the Q&A community to access or modify my invoice.

    Hi Sath,

    Yes, there is an appropriate escalation path. Microsoft’s current Startups documentation specifically lists “program-related refund investigations in partnership with central billing teams” as something Microsoft for Startups Program Support can coordinate.

    Since Azure Billing and Anthropic have redirected you to each other, I would open a Microsoft for Startups Program Support request from Azure Portal > Microsoft for Startups > Your Microsoft Team > Get program support. Reference your existing billing case, invoice number, Anthropic response, and request a coordinated review with the central billing/Marketplace team for a one-time exception.

    The previous $1,000 exception reported on Microsoft Q&A shows that an exception has occurred in another case, but it does not establish a policy or guarantee that the same credit will be approved. These requests are reviewed individually.

    Thank you, and feel free to respond back for more assistance.
