Bad and Disappointing Service

I always have a bad experience with Nandos Protea Glen Mall selling us raw meet, today I thoughtful things have changed. I went there with an open mind and the Cashier was moody it was as though she didn't wanna talk as I was placing the order but I politely asked her to make my full chicken well-done and guess what I received raw chicken still. I feel like crying, I'm angry. I like my chicken well done like how other Nando's restaurants grills it.
