Shoprite return policy

<p>Can someone from Shoprite please tell me how their return policy works and if it applies to their Shoprite Liquor Stores as well. My friend and I had bought, what we thought to be, a 2litre bottle of Scweppes Lemonade at Shoprite Liquor Store in Kuilsriver. Upon leaving the store we realised that it was in fact a bottle of Soda Water. When we wanted to return the beverage and exchange it for the Lemonade, the staff member told us that their policy states that there is no returns on ANY beverage. We hadn't even left the store for TWO minutes. Can someone please give us clarity on this! As I am seriously considering buying my beverages somewhere else</p>
