24pack coke expiring within 3weeks delivered by Sixy60

***A bought 300ml x 24 on 23/12/2023. When opening and drinking the 1st bottle on 15/01/2024 I realised the coke expired on 12/01/2024. Less than a month after purchase. I would like a full refund for the coke yet I am told that I will not get a refund as it was not expired when it was delivered. How can you deliver a 24 pack of coke that is expiring within 3weeks.
