UnSatified customer

<p>I bought an Intel Compute Stick from RussalPC (http://russalpc.co.za) 22 November 2016. When I tested the item, it didn’t work at all. I contact Russal at RussalPC , he told me I have to contact my nearest courier service. So, I did and I paid for shipping again. So, I told him I want my money back. He said, the supplier doesn’t refund only replace products. What if I get a faulty product again? It will cost me money again and again. Please advise me what to do?</p>
