Replacement item not new

I ordered a bluetooth tablet speaker stand from Takealot on 21 May 2015 (order number ***). The one speaker stopped working so I requested a replacement via the website. The replacement was processed and the faulty item collected. I have today received the replacement speaker stand (order number ***). Big was my disappointment when I opened the package and found that the item that Takalot sent me was not new. I am sure this an item that someone else returned to them. I say this because of the following:<br> <br> 1) The actual box of the item was damaged and not even properly closed. <br> 2) The box was not sealed.<br> 3) All the accessories were not in the box (line-in cable missing)<br> 4) The item has got a scratch that reveals the metal below. <br> <br> I have now once again logged a return request on the website and am now waiting for a response and for them to arrange for the item to be collected from me again. <br> <br> I am very disappointed with the level of service from Takealot. How can I be sure that anything else I order from them will actually be new?
