I recently deleted my Azure subscription and the associated tenant. However, I overlooked removing my debit card details from the billing section of the Azure portal before deleting the subscription.
Since it has been over 90 days since the subscription was deleted, I am no longer able to log a support case through the Azure portal due to the deleted directory. Additionally, when attempting to delete my saved payment method, I receive the error message: "If your payment method is associated with an Azure subscription, remove it in the Azure portal."
Subscription ID: 6ecf44d5-5d96-4d50-97ad-72b70980926a Subscription name: Free Trial
I created a new demo tenant and opened a support ticket from new demo tenant. The Azure support informed me that payment method cannot be deleted if subscription is orphaned. So they deleted the details from backend
