Terrible item purchased

I recently purchased a piemans pie from our local shoprite store dated 12/9/24. Upon purchase of the product I had given this item to my mum who had been discharged from hospital to eat she then began to vomit and felt quite ill after consuming the item upon careful inspection we noticed that the product itself was off/Spoilt and had a very very bad smell to it. I approached the shoprite store the very next day stating to the manager what had transpired till date there's been no form of response from piemans itself. How can piemans been the reputable company that you are sell items of such low quality to the public.
