Hi Kavita,
I do not believe you can remove the payment method, but if you have cancelled them than you should no longer be billed.
Delete an Azure billing payment method
The following information helps you delete a payment method, like a credit card, from different types of Azure subscriptions. You can delete a payment method for:
- Microsoft Customer Agreement (MCA)
- Microsoft Online Services Program (MOSP) also referred to as pay-as-you-go Whatever your Azure subscription type, you must cancel it so that you can delete its associated payment method. Removing a payment method for other Azure subscription types like Microsoft Partner Agreement and Enterprise Agreement isn't supported.
