Ill-treatment and worst service

I bought the two bedding sets, one was delivered last week, now I don't even know when am I going to get the second one, at first I was told it is out of stock, I have to choose the other one. I told them they can give me the king size of the same bedding that I chose, up until now I didn't get any response, the worse part I paid. When I bought them they were both on sale, all costed R7100, and now the one I received I was not billed according to sale price. What I expect is to get my bedding set as I've already paid.
