contamited Danone

 hellow Peter , on the 21st of October 2024, I went to buy groceries at MAKRO Polokwane, on my grocery I purchased 4 packs of Danone Nutriday, I opened the pack that will expire on the 23 November 2024, so I packed them in a lunch box of my kids on the 22,23 and today the 24 of October, while my kids have been complaining about stomach ache and I gave them biscopen, so today when i pick up my son from school he complains saying the Danone was not delicious it was testing funny like there oil, and when I get home my daughter asks me where did i buy the donone because they taste like chemicals, then it caught my attention i them open one of the Danone which taste like it oily chemicals.so i took the Danone to MAKRO to explain my story, they told me that they apologise and they would give me a refund and I asked them what about our health because we already consumed that Danone, what do I do in the meantime, they told me that the only thing they can do is to refund my money. then i asked them to give them back the Danone so i will see what to do, but the manager refused to give back , i said they must gave back the Danone because i have the right to know if we have eaten a dangerous chemical, the food manager said he could not give me the Danone back, then i told them that they belong to me now since you do have a solution to my health and that of my kids im taking them back. they then gave me the Danone back.so Peter what do i do now because i do not know what chemical or oil is in the Danone please help,because MAKRO Polokwane was not helpful i dont even have money for consultation at the moment please assist because now im distubed and iam in writing my exams i struggling to concetrate ,please help
