Payment Card Details

My credit card was due to expire, it has been replaced with a new card - same number, just different expiry date and security code.

I eventually discovered the rather convoluted procedure and followed it through. However there does not seem to be any way to confirm the settings. My account shows the last 4 digits, but I cannot confirm that I have entered the correct additional data. Is there any way to do this ?

I was is a bit of a panic since Smarty only reminded me of this ONE day before my next payment was due.
