Very dissatisfied and angry

I went to FatCake city Faitlands and bought a jeal worth R 74.00 (chips and russians). However, when I tasted the meal, it tasted moldy (clearly denoting that the food was either old or the old they used was old). I suffer from extensive diarrhea and because of the food I became sick. I sent an email (because I saty far sad couldn't being back the good) on Monday and all got (from fatcake city snd Stabley) was an apology and we'll look into it comment. I've send follow up messages, to no avail. Unfortunately because the food has stayed long in my fridge, they might say it got ruined because of staying longer in the fridge.
