Money make business and not South African

The sizes of the shoes are smaller. I bought 4 pairs of shoes. After a few emails they let me know that I must buy another pair with a code. I only have to pay the delivery costs. I did it like that. They still charge me 50% of the new pair that I want to buy. This is a money make business. And it is not South African like they advertised. I'm very disappointed in the shoes.
