Returning an item and service delivery is a epic fail!

I purchased a Volkano smart watch, it was used for a few days and I had noticed the battery life is poor, I had to charge it every day but on the box the battery says it last upto 3 days. I decided to return it for a refund which I clearly typed on the takealot app the reason for return is because I am not happy with the battery life of the watch. My return got declined because it was 'used' by a agent on a call. Now how does a customer experience battery problems without using a device? Does it even make sense? On email I get replies from more than 3 different people assisting with my issue and all 3 give me different stories. The latest reply I got from Gillian was my item was already shipped back to me and once I recieve it I need to re log a return and select 'defective' and not 'change my mind', when I initially selected the 'item does not meet my expectations'. The service delivery is poor and also why could they not resolve it when it was in their hands already? This is acceptable and a waste of time. It not worth buying devices from takealot because when something goes wrong they make you run around like you in a circus. DISAPPOINTED!
