Complaint of spoilt juice

I bought a Liqui Fruit Mango and Orange flavor 1.5L at Spar Vincent, when I got home 10 minutes later and opened it there was a strange smell coming out of the juice. I tasted it together with my son as we shared a glass and it had a strange taste and I threw the remaining juice in my glass away and put the remaining in the fridge, later on we experienced stomach cramps that resulted in a runny tummy. I contacted Pioneer Foods on the 28/10/2019 at 08:15am to inform them of the incident, I was assisted by Lee who said he'll complete the claim form and forward it to someone who will resolve the query. I gave out details with regards to the incident, the packaging of the product and my personal details and even advised that I will be going to the Doctor as we still suffered from stomach cramps. I received a ref no: CR19-10-252 at 08:24 am. When I contacted them again trying to find out what will be the way forward, I was advised that someone will contact me early on the 29/10/2019 and everything will be discussed then. This showed to me that the company only cares about its products not the end user (customer) as I have not been updated about my complaint status. All they care of are the tests they run on the juice which I was advised to keep it in my fridge though it's not good for consumption. No regard whatsoever of the fact that I have a child who suffered from their product. I am so disappointed with the service and how this has been handled so far. I wish you could value customer lives more than covering your spoilt products.
