****roach in my big Mac meal takeaway bag

Would like to express my disgust at the way my meal was presented at McDonald's Avonwood. I used a app to redeem 2 big macs and 2 regular fries. When I got to my son's as I bought it for them a ****roach was found inside the bag in which I was served. I immediately never gave it to my sons to eat as I felt appalled myself. I threw it away and kept a pic of it. I figured what's the point in wasting petrol to drive all the way back to the restaurant. Please make sure this does not happen to anyone.
