ROTTEN food

I went to chesa nyama on Wednesday where we bought R300 food including pap and meat upon us buying my partner said the meat does not fresh but we continued to buy , we took it for take away and the next morning when we ate it , it was rotten , both me and my partner realized the food was rotten because of the smell both the pork and the chakalaka was giving off , unfortunately we ate half before realizing it was rotten . today both of us are suffering with a running tummy and cramps that have made it impossible for us to eat further .
