Unhealthy and rotten food

I purchased frozen snoek that had an expiry date of Sep 24. When eating it this week it tasted absolutely rotten. My mum had diarrhea and I was terribly nauseous. I had to drive all the way to the Benmore store to just received a refund with no compensation for my transport costs or notification that someone was looking into this. When I called customer care, there was a no care attitude that they are selling rotten food that could poison and kill people. You shouldn't be in the food industry if you have no care for people's health or lives.
