STORE DOES NOT WANT TO REFUND MY MONEY

I recently purchased a bedroom set on the 6/11/2015 for the value R 35000.00 from Bradlows Newcastle,on assembly of the item by bradlows a lot of defects were seen. I went back to the store and complained. They said they will try and get me another brand new set. After two weeks they told me they cannot give me another as the other bedroom sets also damaged but they can offer me an additional R 2000.00 discount which i agreed to making the purchase price R 33000.00, upon assembly of the rest of the bedroom set i noticed a lot more damages which i then brought to the attention of the store manager. I insisted i wanted a full refund as this is not what i purchased for R 33000.00. The store manager then told me he cannot refund me, he can only replace the set once stock arrives. He also mentioned it can take a few months as this bedroom set comes from out of the country. What are my options in getting a full refund?
