Poor customer service

On the10th May 2025 I purchased an item online and on the delivery day found out that the item i ordered was errouniously placed online. To this day I have not received any feedback regarding my refund after numerious requests for feedback. Why is it so difficult to get my funds back when I was not at fault but the store was and the item was not purchased on credit. Absolutely no compensation for funds i spent and no compensation or accountability taken for a mistake made by the online store
