Makro Online Negative Experience

This is regarding their online shopping platform - terrible experience. One of the products I ordered (12 units of it) was unavailable (although it said available when I placed the order online) - Makro, without my consent, shipped a similar product in place of what I wanted. before the order shipped, I called Makro twice and sent 2 emails telling them I did not want the replacement and to only ship the remaining products I wanted. They did not get that right. I now have to jump through hoops to get the unwanted and unordered items returned before I can get a refund. Terrible online shopping experience and will never shop online from makro again.
