Bad Service @ Online shopping division

This is the worst company i have had to deal with as far as online shopping is concerned. I ordered and paid for a product on 30th of Jan 2025 in the evening. on the morning of the 31st i called and explained i ordered the wrong product and would like to change it and pay the difference. this product has not even been removed from the shelf, so i cannot understand why this cannot be done. I need to wait for the wrong product to be delivered, and then return it, or i can cancel the order, wait up to 14 days for my money, and then purchase the correct item. Makro, if you are not doing well financially, this is the issues you need to look at, as i will never ever buy from you again. People read these comments, and less and less people will order from you. Why can i not just go to the shop and buy the product..... Only available online...... What a ball of ****!!!!!.
