Takealot - not possible to return defective items

I ordered an Philips OneBlade from Takealot, when it arrived I tested it - doesn't work. Sent it back and they are telling me that they cannot take it back because it is used -REALLY? I then wrote a bad review for the product which got rejected, reason is that I should only write about my experience of the product and not the fact when you buy it from Takealot and it doesn't work you cannot give it back.
