Refunding from overseas, terrible communication from Takealot, PLEASE help me!

I am slightly frustrating because there is no way to speak to a consultant at Takealot.

I had bought a bag shortly before moving to London in May. After one flight, the lock and the part of the hard cover had broken. This was communicated to Takealot in June to arrange for a refund. Unfortunately I was told that I need to return it once I am back in SA. I am leaving for SA tomorrow evening (Wed 6 Dec) and have logged a return for the bag. Firstly I was told that the product can no longer be returned (I'm assuming this is a computer generated response as this is not in line with what was communicated to me in June) but that the product may still be under warranty with the supplier. Secondly, I explained in my request that I am arriving back in SA this week, please contact me via email to set up a pick up time as I am not available on my SA cell yet. Lo and behold a courier arrived at my house on Friday to pick it up without anything being communicated to me like I had requested. At this point I have no idea whether the product will be replaced or not or if I should even attempt to travel back to SA with it or not????????
