Pick N Pay The Glen sell rotten Meat

I purchased Tenderised steak from Pick N Pay The GLEN, on Sunday 19/11/17 costing just under R60-00. When we cooked it that night, there were a whole lot of pieces of steak that has gone off. We didn't notice this while cooking but when the pieces of steak were cut open and started eating, we could smell there was something wrong. My two daughters had swallowed some of the meat, when they smelt that it was rotten. Both got sick and couldn't eat anymore supper. When I complained yesterday, I was told TO BRING IT BACK. We had put it in the freezer. I phoned at a bout 15:30 to say I was bringing the meat back. And was told the manager had left already, Another manager Trinity Shai was rather off handed, and said only if we have a doctors account will they pay for it. I asked what compensation. She said they don't give compensation. DON'T BUY MEAT FROM PICK N PAY THE GLEN.
