Hello Justin Gélinas,
Thanks for your question.
I will recommend you first review if any resources are still running:
- Log in to the Azure Portal.
- Go to the "Cost Management + Billing" section.
- Check for any active resources or services that might still be running.
Also, Go to Subscriptions in the Azure Portal and verify if it is cancelled.
For the billing issue, I will recommend you reach out to the support team. You can call global customer service - https://support.microsoft.com/en-gb/topic/global-customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2 to help you connect with Azure billing and subscription management support.
You can mark it 'Accept Answer' and 'Upvote' if this helped you
Regards,
Abiola
