Poorly designed, if a driver looses signal (also know as turning there device off) there is no way of contacting Just eat so the order just gets stuck on delivering. You end up having to trawl through sections to find a e-mail to contact as there app even when the orders over a hour late still says out for delivery, it requires a way of contacting a member such as a phone number as otherwise your out of pocket as the order is forever stuck in waiting for delivery.
