Rotten chips

Hi, Today 2 May 2022 I bought a family meal which cost R249.00. Upon arriving at home I noticed the chips which were served with the meal in the box were not only very small portion for medium chips but also had a very offensive smell. I then realized that we were given rotten chips which were either left to go off inside water the previous day before serving the next day or were just left to rot outside the fridge. Not sure why the person preparing the chips could not pick up that the chips were rotten and instead decided to serve them anyway. I don't wish to buy from the shop ever again as they are not valuing of customer experience or the money we spend buying these meals.
