Rodents at Checkers Warehousing?

I recently did shopping at Checkers Sun Ballet in Kommetjie. One of the item I wanted to purchase was a slab of Lindt Dark chocolate and sea salt. To my utter disgust and surprise, the cashier at the check out till showed me that there was something wrong with the packaging - there were clear signs that the slab had rodent bite marks. I do have a photo of the packaging. Something one does not expect.
