Since the card expired in April I've been warned that my card has expired and that I should change the details. When I try to change the details it tells me I can't because there's an outstanding balance on the account. Now, because the card has expired, it won't let me transfer the money out. I'm told to telephone support to sort this out.
Back at the debit card: I called telephone support this morning. I waited about 40 seconds or so before a nice chap apologised for the delay in answering my call. He then asked me some security questions and then checked the account. "Oh, I see" he said, "try again in half an hour, we'll allow the change".
That was this morning and I've just tried again. No joy, so I thought sod it, they can have the 10p. But of course, I can't close the account while there's a balance on it. But again, it didn't tell me this until I'd worked through entering a reason for closing the account* and through the "transfer outstanding amount" screen.
* Maximum 100 characters, but you're not told this until you've entered more than that.
All in all, a very poor user experience. Well done Camelot!
