Soda in bad condition

My name is Xolani Zikhali I reside in Durban central. On the 27th June I went to spar North Beach to buy myself a Scheppes dry lemon, I bought two 1 litres but when I got home as I was about to drink it I noticed that it had funny flouting things inside. I went back to Spar spoke to the manager and he called a Coca cola rep and they were suppose to come back to me but they didn't.

My concern is that what if I had drank that and gotten sick. The inconvenience they've put me through, my petrol going up and down to the shop.

I want them to sort this issue out before it gets out of hand.
