Smelly Chicken being sold

I purchased a few items yesterday, at Pick 'n Pay Kenilworth Centre. - Part of it, was 3 packs of chicken breast. When I got home, I packed the chicken in the freezer. When I opened the 3rd pack, I immediately got an old dirty smell. The chicken was OFF. Turned it around, and it was already turning blue. It smelled sooooo bad. I returned the item about an hour later, and a lady gladly assisted me with a refund. Even when she opened the pack, she had to turn her head away from the packet due to the stench.<br> <br> My thing is - how can you sell goods with such bad quality? Who does your hygiene checks? Who checks that the products are still fresh on a daily basis? What if someone else actually cooked it, and got food poisoning?????
