Apple ID Not Allowing Me to Change Payment Method

I have done exactly this several times now - Go to Apple Store - Click on my name - Click on Account Setting - Annoyingly have to sing into my account, so sign in - Manage Payments - It shows me my payment method has expired in a big red box. WELL YAH! NO S#@%^^@$*! - Then, when I go to update it, the system will not allow me to do this. If I click on Remove payment method, It will not allow me to do this. If I try add new payment method - IT WILL NOT ALLOW ME TO DO THIS!!!!!!!!!!!!!!!!!!!!!!!!!! I enter my new info and another red box appears saying contact you people. UGH!!!
