Checkers delivery guy dropped my grocery to another house

I bought my grocery from checkers 60 60 and the delivery guy delivered my grocery from another house in my complex. He entered the complex using my own code I gave him and I was surprised that my grocery was not coming and I have waited for this grocery for almost 3 hrs as I ordered around 10 for it to be delivered in a wrong house at 13h00. I just got a message from the whatsapp group in our complex ( See attached text from whatsapp group )Hi, i have received a checkers delivery for unit 51. The driver just left it here at 58. Please come and collect it.

After receiving that message from the group i didn't know how to get hold of the guy as he stopped the trip. I went and collected opened bags 3 of them where opened. When I call for help I was told there is nothing they can do with it hence I told them im not going to eat opened food from somebody's house i don't know can I please have my refund you will come and collect your food. Nothing was done and I was told if they will refund me which means I won't be able to buy again next time. Till now my money is gone and I had to throw away all the grocery. Im so disappointed.
