I have been doing weekly online grocery shop from cornelscourt since November 2023, at the start I was very impressed with the quality and the picker sticking to my list, the delivery staff have alway been extremely helpful and friendly and consistent on delivery time. However the last 6 weeks I have noticed the complete and utterly disregard for picking what was on my list. The person picking my shopping clearly couldn't careless what I had taken my time to write on my order. then each time I contacted customer service about these issues they pawned it off as it was a my fault issues. Having clearly written substitute with.. I was told I had to tick the box, so the following week I do that giving my alternative again, this time I was told alternative had to be from same aisle, following week I amend my order to follow their "rules" and still get stuff I hadn't asked for the next week I did the same and wrote only substitute from my listed products.. again falling on deaf ears and getting random stuff put in. Then last night I had 3 alternatives on some items and they picked none.. I find it hard to believe such a big shop with be out of all 3 options of main brand sausages along with other items and then they put in a drink I didn't even order nor did they highlight that they substituted it. Zero response from customer service who said they passed it onto cornelscourt online grocery manager. They also never notify you of items returned like most places do when you send something you didn't order back. As a result of their lack in customer care I will no longer order from their online grocery platform. Both Supervalu & Tesco offer a fast superior online customer service and read ones order.
