I made the payment using an Amex card, and it was processed by GoToGate (booking.com's associates in this venture). GoToGate then paid Ryanair via Mastercard (according to Ryanair's email to me).
I have opened a dispute with Amex, which they are pursuing. In any case, I've rebooked with BA. Serves me right for not doing this in the first place, but lesson learnt.
