They should accept Visa and Mastercard. I never bother, because Maestro
always works. Didn't you try that?

Only about half the UK banks issue Maestro debit cards. The other half
(including mine) issue Visa Delta debit cards, which are accepted
pretty much everywhere Visa credit cards are. This is usually a bonus,
but can be awkward in .de and .nl where Maestro is far more widely
accepted.
