Found a fly in the food

I bought soulfire meal, which is 3 chicken pieces and chips at Chicken Licken Durban West street. As a take away. When I got home I had 1 piece and as I was about to eat the second one, I saw a fly and I looked at the big piece and it had the flies **** ( small tiny white things all over the meat). My food was cold as a dog's nose showing that they gave me food that was prepared a while ago. I am so disgusted. It a shame.
