I placed an order for four one liter bottles of ink for my printer,but received the wrong ink. When I wanted to log a return I found that 'this item is not returnable'. It was like my money was ****** right in front of my eyes and I can't do anything about it. I'm definitely buying less and less from Takealot and will advise everyone to do the same.
