Poor Customer Service

I have placed an order and after paying i realized its not the item i want, i phone them and ask for cancellation and was told because my order is out on delivery i should wait until its shipped to cancel and i did that . My order got delivered and i rejected it which was an advice i got one of their agents . The next day my order came back and our reception signed for it. I logged a return immediately and went to drop it and now I'm told to wait 2-3 working days to be refunded. I mean I did not even open the packages and I have requested cancellation before it was delivered.
