I placed an order for two pairs of sneakers on 26/08/2022, and recieved an email that my order was processed. Later in the day I get another email saying that my order on the Nike Air Haurache was cancelled and was given a voucher of 10% which amounts to R220 while I would hve saved R560 on the initial order, their reason was that there was an inventory error. I just think that they are ******** me because why can't they replace the order to give me the same benefit as opposed to half of what I was going to save?
