Hi Mart F,
Apologize for any inconvenience caused on this.
You have been locked out of your Azure account because your Multi-Factor Authentication (MFA) method was deleted. This means you cannot log in, access your subscription, or manage your billing. Here are a few steps you can follow to resolve this:
You mentioned that are already tried various support channels, so I recommend reaching out to Microsoft Account Recovery Support specifically for Multi-Factor Authentication (MFA) resets, follow this link:
Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID | Microsoft Learn
If you prefer to delete your subscription in the Azure portal, go to the Azure Cost Management + Billing page, In the left menu, select "Subscriptions" and choose the subscription you want to delete, navigate to the top of the subscription page, select Cancel and select the reason for cancellation and, if applicable, turn off auto-renew for any support plans. If there are running resources, turn them off. Then select Cancel subscription to finalize.
After cancelling your subscription, Azure will close your current billing cycle within 72 hours, and you will receive your final invoice, and your data will be preserved temporarily in case you decide to reactivate your subscription.
Kindly follow below detailed documentation links for the process:
