Takealot refusing return of Faulty Product.

Bought a laptop charger. Supp**** charger did not look like the picture on website but it was a working charger with the correct tip and voltage for the laptop. Charger went faulty after 3 months. When returning the charger Takealot refused to assist as the charger does not look like the item in the picture. Tried putting a 1 star review on the website to warn other people and the comment/review gets rejected.
