Off and Smelly coocked food from checkers

I bought food there more than once . The food was off and smelly. The worse part is they know about it . I'm a xhosa speaking lady so they assume I don't understand Afrikaans so the manager and the lady who assisted me with the they argue infront of me in Afrikaans . The manager was asking "didn't I ask you to take the carrots away and leave yesterday's only there" ? He went and refunded me. My colleague sometime last week bought a snoek fish It was smelly she ate a small piece the she notice the fish is smelly, after eating that small piece her stomach was running . I will never buy cooked food there .
