Simply chicken Vienna's makes me sick

Hi I have been a customer of simply chicken products from a long time but last month I purchased a pack of simply chicken Vienna's from my local supermarket Check save.Upon eating it it had a terrible smell and tasted horrible and made me vomit.I assumed it was from the heat hence I didn't do anything.I purchased the simply chicken cheese viennas again last week from my local spar and the same thing happened when I wanted to eat it despite it being a normal weather day.Other people who is currently working with me is experiencing the same thing so this can't be a coincidence.As far as I remember these Vienna's used to be the best tasting thing amongst all other Vienna's .I have a whole pack of Vienna's lying there which I purchased from my hard earned money that I cannot eat.I would like assistance on this. Thank you.
