We booked a slot and made an order 1 week before the requested delivery date. We were able to edit the order until the night the day before delivery. However we were notified in the morning of the delivery date that some items were not available with no option to add new ones. Given the current situation we didn't take too much notice. During the day we got an e-mail that the delivery would be an hour or so late. Again, we didn't make a fuss about it. However 10 minutes after our delivery slot, the driver called us to inform us that he has no more driving time and can't make the delivery. Our order essentially cancelled and we couldn't reach ocado's support chat or line. After 1:30 hour we saw at the website that we could book a new delivery slot after two weeks. This is totally unacceptable. They pride in 1 hour slots. They should try to make the deliveries and take pride on delivering an actual service. We'll never use Ocado again. Totally unreliable, with no customer support.
