Non delivery

I bought a Contessa dining room suit on the 8th of January 2015, when the delivery was made after 2 weeks, only to find that the side board was damaged, then I contacted the store the following day to lay a complain and then I was told that they will forward the complain to customer car so that they can send me a new side board, then in March the evaluators were send to my home to check on it, and the report was written by those evaluators to confirm that the side board is not in good terms it need to be exchanged. I have been waiting for the exchange since then, and on the first week of April, they send people to come and collect the side board from my home without replacing it, Every time when I call customer service I am given reff numbers to tell me that they are working on my complain. Till today I am still waiting for my side board to be delivered, My reff numbers are *** and ***. If tey are not prepared to give my side board back please give me my money back because I am tired of them taking me from pillar to post.
