Misleading expiry date

I bought a bulgar wheat and quinoa salad with feta and green pesto at the St. George's Mall branch. When I got home and opened it, there was a very strong odor as though it was past its expiry date, even though it stated it was made on the day and it should be consumed on the day. I ended up having to throw the salad away because I couldn't return it as I live too far from the store. Very disappointed, never expected this from Woolworths.
