There has been a real deterioration in customer service with online grocery shopping from Sainsbury's. The drivers were always great, but more recently have been grumpy and do not distance. Too many unavailable items. And they never tell you about substitutions at the door or short-life products, unlike Morrison's delivery drivers.
I know they send you an email receipt with all this in, but I find the Sainsbury's delivery drivers often come early and so I have not had a chance to check the email.
You have to ring up for a refund, and even here the customer service has decreased. I mean it is okay, the refund gets processed. But I have spoken to a number of people who just sound like grumpy teenagers going through the motions.
I wish I hadn't bought a delivery pass now.
