Hello shawn kelley,
Thanks for posting your query in Microsoft Q&A forum
As a Microsoft employee with a large, unexpected Azure bill on your personal account, you can request billing support to resolve the issue. All Azure customers, including employees using personal accounts, have access to free billing and subscription management support without requiring a paid support plan. You can create an Azure support request for billing issues to get help identifying what caused the charges and how to correct them.
While there is no direct public mention of Teams contact specifically for employees, opening a support ticket through the Azure portal's Cost Management + Billing section is the recommended channel to get personalized assistance from Azure support teams.
