FAULTY WARDROBE AND DONT WANT TO EXCHANGE IT

I bought a wardrobe at Louis Trichardt, it was delivered on the 28 Feb 2015. They sent the people to assemble it on Sunday evening (01 Mar 2015). My mother notices that it is faulty on Monday morning because it was assembled at night. i called Mr Modau and informed him of the faults and cracks,he sent someone to go and repair it. The guy repaired what he was able to and left some staff unrepaired. Then my mom called me and told me the report and when i told Modau he said he will go look at it because he don't want to exchange it instead he wants to keep sending people to repair it. The repairer said the wardrobe need Masonite. now when i call him, HE IS IGNORING my calls.I WANT AN EXCHANGE i can not afford to keep a faulty product in my house. My mom is the one who is informing me as i am away from the product.
