Saved CC location in new British Airways Club!

[Stewiw1961]

Can anyone help with the following…
Where is the Saved Credit Card details stored on the new British Airways Club www/App, as i need to change CC details.
I have been trying to book flighst using a 241 voucher and my saved CC details need to be updated as the booking is continually rejected. I have tried entering this as a new CC but BA Club keeps reverting back to the saved CC,and i cant overright with the new expirey date. Tried calling helpline and booking line but no answer. Total bloody usleSS ba. If anyone can help with this will be apprecaited. Thanks

Not a location as such, but book a flight, pay using add a new card, and store for future use, then cancel the flight within 24hrs. This method of adding new card has worked for me, although I’m keeping the flight, and when I do a dummy booking for another flight the new card has appeared as the default payment option….
Of course that may just be a BA IT quirk but has worked for me.
