KFC sell poisonous food

I have bought 2 Festive feasts on 31 January 2023 at KFC in Jean avenue Centurion. The food just tasted off and my wife unfortunately got the bug which landed her in ICU. She ate the chicken and immediately did not eat anything else but was to late. After getting sick Sunday evening which did not stop till I took her to hospital on Thursday she was admitted to ICU with severe Salmonella infection. She was in ICU for 5 days and nearly died due to the infection. I did write a complaint on the KFC official website on Sunday 7 January for head office attention and still await reply on this. I will never get near any KFC again and will spread the word far and wide.
