No Delivery, No Response

I bought a dishwasher at Makro online 29 Sep 2017 and after waiting patiently for 21 days I had to call them to find out why now I was not receiving my goods, they told me there was a delay which no-one bothered to tell me about. They gave me a new timeline which also passed and I was the one who had to call them again to find out what is happening, which they told me they received the machine but the box was damaged so they opened it to check if it was damaged and they will deliver it to me bubble wrapped. I refused that as I don't what else could have been damaged and they said they will order a new one. A few days later I followed up how far was my order, they told me the machine is no longer available at the supplier and they offered me a substitute which was not comparable to the one I bought including the colour, being white when I ordered stainless steel. I have not heard from anyone since, calls go unanswered or the person is not available and there is no response to my mail.
