Hello Kevin,
proceed as described below:
Check your Azure billing overview
Sign in to the Azure portal.
Navigate to “Cost management + billing”.
Check the detailed cost breakdown.
Check active resources
Go to “All resources” in the Azure portal.
If there are still active resources that you do not need, stop or delete them.
Set a billing limit
If you have not defined a limit, you can set up budget warnings and spending limits under “Cost management + billing”.
Contact Microsoft support
If you are not sure why the costs were incurred, you can contact Microsoft Support directly and request a refund or clarification.
If this is helpful, please accept the answer. Thank you.
