Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
Go to the Azure Portal and open the "Subscriptions" page to check if your subscription is listed. If it's not, make sure your account has the necessary permissions to access the subscription.
Review your role and permissions in the Azure portal. To manage billing and view payment methods, you may need to have the "Owner" or "Contributor" role on the subscription.
If you are still unable to resolve the issue, it might be best to contact Azure support for assistance.
