I've been shopping online for groceries for about ten years. I have nothing but praise for Ocado. Carefully picked groceries, great range of products to choose from, easy to use ap, professional drivers that actually seem to like their job and an amazing customer service team that resolves even the tiniest of problems pronto. No, not all online retailers are as good. I know this because I switched to Ocado after receiving cat food as a substitution for chopped tomatoes, badly damaged items, half of the delivery missing and a driver shrugging it as " these things happen". Yes, these things happen, we're humans after all. It is how you deal with the problems that matters to customers.
