Cannot return item Makro Online

Bought a product from Makro Online. When it arrived, I found that it was really not what I was looking for. So, I proceeded to log a return, just can't do it. On your profile in the Makro App, you will find a returns section. Mine shows that I have no orders. So I cannot log a return. On their side, they can see the product bought and delivery status, but they still cannot log a return. I have recently received an email saying that I should download and install a new internet browser to help iron out any creases on their site. That's just crazy. Now, I am sitting with a device that I will never use AND I'm out of pocket. I have been trying now for over a month and have had no luck.
