Poor service

I returned a stylus as it was defective. I asked for a replacement product, however I was told by Takealot that the product is not in stock. When I went on their app, the product is still available to order. I provided this information, as well as an alternate product (within 24 hours of receiving their email). Takealot then processed a refund without processing my request for an alternate product. They now expect me to pay for delivery on an alternate product, when I paid for delivery on the initial product! I am thoroughly disappointed that my request was not attended to and Takealot just made a decision. This is not the level of service one expects from Takealot. #lostcustomer
