Ocado have had a lot of problems as people who do not normally use them signed up in droves at the start of the COVID-19 outbreak. They are working hard to cope at the moment and things are improving all the time. I have used them since they started up and have always, including during this crisis, found the drivers conscientious, hopnest, polite and helpful. It might be that they have some less experienced staff at the moment, but I have never encountered a bad 'un. I had one item delivered in my last load of shopping that was not as good as it should be and they refunded me the cost straight away with no argument.
