Two things that would be very helpful from every billing page…
1. Have a button that allows users to retry paying an outstanding payment With the existing card on record rather than the user having to put in their same card details again and again.
2. every billing page should clearly have a button to contact customer support. When payments don't go through or if there is an issue with payments, it is the single most stressful part of any customer interaction. And the point at which any business should make every effort to resolve that as quickly and as comfortably as possible. Having to dig through menus and other pages to find customer support each time is not a good look.
