Hi DH0530,
Thanks for posting. I see you have a question about your AppleCare+ payments. This resource has some great information: How to manage your AppleCare plan
If you pay for your AppleCare plan on a monthly basis, you can manage or cancel the plan from your iOS device, Mac, or PC. Learn how to cancel your subscription.
If you don't see your plan, finish setting up your account online, then you'll be able to manage your plan and how you pay for it.
If your AppleCare plan still isn't listed with your other services, or if you need more help, contact Apple Support."
Based on the above, if updating your payment method hasn't cleared things up, I recommend getting in touch with Apple: Contact Apple Support
Take care.
