Spoiled chicken & failing to refund me

I am so disappointed, I am only posting this because they failed to resolve my issue when I was instore. I recently bought chicken meal at Steers Westville Mall and meat was off, smelling before it was cooked. Likely I opened food before going home. I returned the meal and the indian lady kept lying saying the chicken is fresh. I mean why would I return fresh food??? Anyway, she added lies with the person she was calling and said its the mild sauce that was off, they gave me hot chicken, it was still off and dark. I don't know a fresh chicken like that. I requested a refund for chicken then I would take pap and salad and she refused and said I had eaten the first chicken, I don't know who touched the chicken inside their kitchen course when I brought it, I had touched the drumstick side and couldn't eat it but when they brought it back they said I had eaten it. By the way I had to leave everything, both meal and my money....I really regret. Meat is not only smelling, it is even darker
