Supp**** with rotten beef bones

I was sold rotten beef bones this morning at 08:48. I wanted to prepare soup with beef bones for my family. As i opened the packaging, the smell was horrible. I quickly phoned the store which i was transfered to the butchery department, spoke to the lady called Nokubonga and she said they could have given me dog bone. My question is, why keep rotten/ dog bones with consumable meat that is ready to be sold to consumers. She confirmed to me that the bones could have been for Dogs. Shocking, the packaging was done on the 5/06/23 and already on the 6/06/23 the bones are rotten Why sell us rotten beef bones? And to my surprise the lady just responded by sorry you can bring them back, they will change them for you. Do you really think i still want to buy the bones after i was told they could be for Dogs?
