[Others]How to delete my payment account ?

I want to delete my payment method please help me,i didn't find any options regarding the deletion of payment method.

Alibaba Cloud does not support users to delete their payment methods, as it would potentially interfere with outstanding fees.

Check out the point number 3 on the following link:
https://intl.aliyun.com/help/faq-detail/44175.htm

"Suspending your account does not automatically remove any user information or payment method information. You must log on to the console to change your account information.
If you want to remove the default payment method, you must clarify that in the ticket you open. (Note: Any requests for deleting all payment methods with outstanding charges is rejected by Alibaba Cloud.)"
