No happy with servive

I bought a washing machine cash at Protea Glen branch om the 30th of July. And it is still not delivered.... I have been calling and calling and being told different stories. Only today I was only told that it is out of stock even with their suppliers and I asked for a refund and they told me I need to give them to raise that money as they don't it in store... Please help with my refund I don't want their machine anymore
