Zando Return to Ucount

I purchased some items from Zando using my Standard Bank UCount rewards card. After receiving the goods I requested a return and chose the option "Return funds to UCount". Once the return was processed I received a mail stating that the refund had been made in the form of a Zando store credit. On calling Zando, I was told that they do not refund to Ucount and that is why a store credit - this is apparently outlined in their T&Cs. This is unacceptable, why have the option to return to Ucount if it is not possible and then to "hide" this fact in T&Cs? I would never have purchased on my Ucount card if I had known that I would not be able to refund back to the card. I am now tied into purchase more items from Zando.
