Do not use Sainsbury's online: 1. They failed to deliver half my order; 2. They substituted a red wine for a white wine; 3. They delivered the order 2 hours earlier than booked (and as a result I was not present to check the order and discover 2. above); 4. As a result of 3. I am "deemed" to have accepted the order; 5. I now have to take the white wine that I do not want back to a store to obtain a refund; 6. They substituted prosecco for a more expensive prosecco, but charged me for the more expensive one, not the cost of the one I ordered; 7. After 30 minutes on the phone they finally accepted I was correct about 6., but rather than issue me with a refund, they have issued a voucher, forcing me to spend the voucher at Sainsburys! Will never use again.
