I just heard back from CashCase. They say:

"If you are making a purchase in a currency not supported by your card, for example the rand, your card will look to draw funds from your British Pounds purse and the exchange rate applied will be the prevailing Visa exchange rate plus a 2% international transaction fee will apply."

Kind regards
