No access to test-tenant and want to stop billing Azure Blon

To stop billing for your Azure Blob Storage associated with the tenant you no longer have access to, you will need to cancel the subscription linked to that tenant. Since you have forgotten your credentials, you will need to regain access to the tenant to proceed with the cancellation.

Here are the steps you can take:

1. Recover Your Account: Try to recover your account by using the password reset options available on the Azure portal. You may need to provide information related to your account to verify your identity.
2. Contact Support: If you are unable to recover your account, you can contact Microsoft support for assistance. They may help you in recovering access to your tenant or guide you through the process of canceling the subscription without access.
3. Cancel Subscription: Once you regain access, you can cancel the Azure subscription directly through the Azure portal. If you have a free trial or pay-as-you-go subscription, you can delete it three days after cancellation. For other subscription types, follow the cancellation process outlined in the Azure documentation.

If you are unable to recover your account or cancel the subscription, it is essential to reach out to Microsoft support for further assistance. They can provide specific guidance based on your situation.
