Don't Buy from Oh My Goodness on Takealot

I am an avid Takealot shopper and am normally very happy with my shopping experience, until I attempted to purchase a Crystal infused water bottle. The company advertising it the most, "Oh My Goodness", has cancelled my order 3 times. Each time I have selected another crystal and each time it takes about a week or two and then I get a notification that my order has been cancelled because they cannot locate the product. Why is Takealot still allowing this company to use its platform? I don't even want to purchase from Takealot again because of this.
