I've no idea what the status says since it's not in English, but looks like it's stuck in a Pending state due to their payment method failing at Quickpay? They can cancel the basket themselves from the baskets page, does that not work for them? Do you have any notifications in CBSubs > Notifications indicating why it failed? The order id already in use error is a Quickpay error; they don't allow re-using order id.

The acquirer (payment processor) rejected the payment. Quickpay doesn't release the order id in this case so the basket needs to be completely cancelled and regenerated. I don't have a solution for this beyond them clicking the cancel link at the bottom and retrying.

Normally a order, or payment, shouldn't be locked in when there's a refusal. Other payment providers do not do this. So we don't have a built in solution for this strange behavior Quickpay does. I've added a feature ticket to see if we can automatically cancel, regenerate, then redisplay the basket when this happens but am unsure of how well that'll work at this time.

A basket in a "Not initiated" state should be expiring though. It's strange that it's not. That usually only happens if it's in a Pending state.
