Expired food re-labelled

Bought pre-cooked sosaties from Superspar in Westwood on 09 June 2015, and after my kids ate it they got sick with diarrhea the next day. I knew it was the food bought at Spar as that was the only thing they had for dinner. I checked the packaging and found that the sosaties show a sell by date of 12 June 2015 with another label placed over this label with an expiring date of 01 June 2015. I took pictures of the packaging and on 12 June 2015 visited the store. <br> <br> This was the most shocking part where the manager Jaco van Schalkwyk first refused to accept that it happened. I then showed him the pictures and even more of the same product with two or more labels on the shelf 3 days later. He was very arrogant and said these things happens and because I had no medical bills they will not really accept it. They offered me compensation in chocolates for the same value. I refused and ask to speak to a senior manager and they refused after several attempts I finally got hold of the Regional Ops Manager, Alistair and he also was full of excuses, as I was not allowed to contact him. I was then contacted and promised an explanation and Spar card. This never happened. Disgusting!
