Rotten food

Good Day<br> <br> An hour ago i bought a meal at Checkers in Walmer 6th Avenue(Port Elizabeth), which consists of rice,stew,sweet potato,butternut and a piece of chicken.. food didn't taste good at all the butternut was rotten and soar that messed up my whole meal i've got tummy acre and i lost my appetite, i went back for my refund which i got,however nobody had an explanation of what had happened. many cases like these had happened to others too that's why i feel like at least one should warn others about this, it is summer time we deserve fresh food.
