Rotten meat

I am very disappointed, I bought meat last week Thursday before our weekend away it was packed properly with ice in the cooler and the drive was only 100km out of JHB. We got there and took the meat out to braai only to find that the big tray of pork rashers and hamburger patties were all rotten. I couldn't drive back to jhb to exchange and we were in the middle of Parys. What a waste of money and the fact that we lost food.
