Rotten food

Shoprite South Africa I'm really disappointed I bought a cake for my mother yesterday to celebrate her birthday only to see the cake is rotten and my kids has runny tummy. There's a receipt is attached with the cake on the picture. I bought the cake at @ shoprite dawn Park Shopping center. I want a refund, I'm working today tommoro I'm taking my kids for consultation and want them to cover that and NY petrol. I'm working today after work I'm taking back that cake to the store.. My number is ***.. I'm really really disappointed
