Anyone experiencing problems paying Aqua Card?

Fingerbobs

The WorldPay system for debit card payments is rather clunky and amateurish. Aside from not working if you use a popup blocker, all the text seems to suggest you're buying a product from SAV Credit, rather than paying a credit card bill. It even concludes by saying "Thank you for shopping with SAV Credit!" and the final screen of the payment process has some text "Return to your Account" or similar, but it's not a link. You're left in limbo, and just have to close the window.

Not very professional at all.
