Could not publish an honest product review on Takealot.

I bought a 40kg Barbell/Dumbell set via Takealot. I recieved a 30kg weight set and not 40kg. I don't feel like going through the whole process of returning the original etc. Apart from the driving around I have to pack 30kg's. Point is : I tried to write a review on the product to that effect and my review was rejected by Takealot. One cannot even trust the reviews as Takealot doesn't allow their customers to be honest.
