No one from Nadec or any co., would respond direct to customers, they are supplied to outlets and it is their headache to deal with your complaints. Some times the merchandisers or the shelf man might rotate the old stocks ( not follow FIFO basis ) or not properly stored in a cool temperature etc., are the few reasons. But the general rule is any food item which has short shelf life ( less than 3 months ) should not be displayed / stored. It is better do not buy items that has very short life.
