Rotten chicken from chicken licken

I just bought Soul Sister 2 from Chicken Licken @ Silver lakes and the pieces i got, one of them, which was drumstick was rotten and because I bought takeaway, I only noticed when i was about to eat it and i was already far from the restaurant and the smell.was horrible, couldn't go back as I was already far. I'm sure they were aware of the it being rotten as the smell was horrible but they sold it away. I will never again buy from chicken licken. I am very disappointed customer
