Damaged incomplete goods

In September 2015 i purchased Monte Carlo 7 piece dining room, side board and welsh dresser for cash amounting to R18 000 for my grand mother's house. Firstly they delivered incomplete goods without the side board and when i made follow ups was told it is out of stock. I reported on hello peter and then it was delivered to my grandmother. I thought all was well until i went to visit my grand mother last saturday (27 Feb 2016) only find out that the side board has scratches and it does not have inside glass dividers like it should be. It clearly shows that joshua Doore takes my business for granted by delivering damaged incomplete side board that was used for display in order to respond to hello peter's query. I want Joshua to collect their useless damaged incomplete side board and replace it with the a brand new one or refund my hard earned money back. Poor service and taking customers for granted.
