expired baby goods on shelf

Hi My Name is Rovanie Pather, last week Monday went shopping at the Springfield Makro where by my husband and i purchased a number of items... one of the items that i bought was the Nestle Jogolino yogurt. As a customer when i buy a product from a store i expect the product to be safe to eat and not expired but to my surprise on Saturday when i was feeding my baby the yogurt i noticed it did not look normal so i decided to check the BB date which was the 22/08/2017. i am so angry that my 10 month baby had to eat this expired food. how careless can you guys be and mainly in the baby department. i have sent and email today to Makro with my tillslip and a picture of the yogurt. i have got no reply as yet.... how can i trust this store again and buy anything from here knowing that you guys are so irresponsible...
