Misleading product information being allowed

I have ordered toner from Takealot. The wording of the listing read as follows: BULK Pack Cartridge - Includes all 4 colours Only the black toner was delivered. I have tried to put in a review to warn other potential buyers of the false advertising by Takealot's Seller, but Takealot is refusing to allow my review. I have tried to be very respectful and diplomatic, using wording such as 'product not as advertised', but they still refused to list my review and they have not removed their Seller's listing. Although Takealot has refunded me, in my opinion, not allowing a negative review goes against the right to voice your fair opinion about a product in order to warn / caution users about false / misleading listings / sellers.
