The easiest way to update your credit card details is to use the link sent to you on a renewal invoice. (although note that the payment for the next month will be taken immediately when you do this)
Otherwise you can ring our billing department.
We are aware that the billing section of the portal needs some improvement!
However it is possible to do it via the portal if you follow these steps:
1) Go to the "My billing" section, and select "Services Billed o me"
2) Put a tick next to all the services you wish to update the card details for
3) Click the Blue button above the list "Select Services"
4) Click the "Change Payment Method" button that has now appeared at the top
A wizard opens which allows you to change the payment method to a new card. The steps from now on should be reasonably obvious.
