Hello Anthony,
Thanks for reaching out on Microsoft Q&A.
If you are being charged despite having Azure credits, I suggest contacting the Azure Billing Team to investigate the charges associated with your account. They can help verify if your Azure credits are being correctly applied and identify the root cause of the issue.
You can create a support request by following the steps outlined here: How to Create an Azure Support Request
Additionally, check your Cost Management + Billing section in the Azure Portal to review the services incurring charges. Ensure your usage aligns with the services covered under your Azure credits.
Hope it helps!
