Sainsburys Ferndown repeatedly ignore the timed delivery slot. Delivered 10.20am instead of the booked and confirmed 12-1pm slot (not good when I worked late and needed the sleep!!). Not the first time this has happened either, the same happened last week. Also, I was not informed there had been substitutions and therefore didn't know to check I was happy with the substituted item which I'm not. Finally, yet again the store picker clearly doesn't know the difference between products and puts items such as a lime through as a lime but actually has delivered a lemon! Today, yet again, I didn't receive the item I ordered as the picker had chosen the wrong item. Sainsburys is my preferred store for groceries so I'm gutted that I cannot trust to shop with them for my online deliveries any longer as certainly my local store, Ferndown, Dorset consistently gets it wrong.
