Overall, I am happy with the ocado drivers that deliver to me twice a week. The one thing that annoys me when the order I either late or early and the driver doesn't contact me. When a driver has the opportunity to deliver early and the time is before 8am I would like to receive a text message asking if it is ok to deliver. On two occasions the driver has turned up at 6.20am, waking up the whole family, when my delivery slot was 7-8am. If they are early, and the time is after 8am, they can call and ask. I would really appreciate a call when a driver is running late. I know that drivers are sometimes sitting in traffic, where it would be illegal to make phone calls, besides calling up-coming customers will result in delaying deliveries even further, therefore I think that a driver running late should send a message to ocado HQ where someone will be able to call all his up-coming deliveries and provide them with an expected deliver time.
