Return Policy protects the Business and not the Consumer

I purchased over 2kg cheddar cheese in total on 16 January 2022. I had kept 2 blocks in the fridge and when I wanted to use it there was 2 white mold like spot on it. I took this to the North Beach Spar on the 1 February to request for a refund and I was told by the Store Manager Mike, that their returns policy is 14 days. I was surprised as this is an item that has spoilt and I am returning it on the 16 day. I was also told that perishables must be returned in 24 hours, and on request of this notice, I was pointed to a small board at the cigarette counter with the return policy. I was also told that my fridge may be a problem that is why it spoilt. I was refused a refund in spite of me showing the spoilt product,
