Rock hard Tinkies on pick n pay shelves

On 15/01/2016 I went to pick n pay hyper by the sea Durban north and picked up Tinkies which were rock hard. These should not have been on the shelves in the first place. I requested to speak to a manager and Quen the bakery manager came through. He was rude and insulting as well as laughing at me. He said Tinkies are supposed to be hard. He refused to listen to my reason . I then spoke to another employee who said that Tinkies are not supposed to be hard. Quen then threatened me saying that if I complain I will get in trouble with pick n pay international. I then went to customer care and spoke to a lady who never did anything but said that Tinkies are not supposed to be hard and it should not have been on the shelf. She never did anything or apologize. Disgusting how pathetic employees and management is of such a huge retailer. Really disappointed and will tell everyone I know not to eat anything from a pick n pay as it is disgusting to keep such poor quality products on the shelf which can cause food poisoning and sickness. Really sickening customer treatment.
