Poor service

On 19 of November I bought Rhineston syrup the big bottle at clicks Faerie Glen when I arrived home I realized the expiry is 11/2024 and still have the slip tried to buy another one at Waverley clicks and it also had the same expiring date. And the slip I had there was nothing at the back written about conditions When I try to exchange it was told they can't it's against policy yet it's not against policy to keep on shelves medication that is left with a week to expire
