Fly eggs on my chicken

I am extremely disappointed at Galitos Walkerville. I bought food 2 weeks back. I stay 2 min from the store snd began eating my meal (chips and chicken pieces) when I noticed fly eggs on my chicken. My daughter refused to eat her meal after seeing mine. I closed the meal tightly in a bag and stored it in the fridge. The next morning I took it to the store and politely exams what I found. I sent the manager the pictures I took if he did not want to open the packet. He said he will speak to his Manger and get back to me. No word for 2 weeks and when I contacted him he told me that there is no way this happened on their side and I won't be reimbursed. I don't even care about the money but they refuse to take accountability.
