Spoiled chicken from PNP Vereeniging and cake

I purchase chicken pieces last week Tuesday at Pick n Pay Vereeniging. When I got home I could smell some was awful however I gave it a benefit of a doubt. On Friday when I tried to fry it was indeed rotten because the smell was all over and there were flies in my place. I feel unfairly treated with my last cent,thinking I would have something to eat with my family only to find this. The cake I also bought was outdated already. I feel ********** by the store.
