Hello دانه بنت منصور الزهراني
Thanks for your question.
For this I would recommend you contact billing support. To do this create a ticket at https://azure.microsoft.com/en-us/support/create-ticket and make sure to select billing.
In the meantime try the steps here https://zcusa.951200.xyz/en-us/answers/questions/836009/cant-detach-the-payment-method-credit-card as this solved the exact same issue when experienced by another user.
Please let me know how this goes.
