Makro Purchase - New Samsung Machine Defective

I purchased a Samsung washing machine in March from Makro- Invoice 4E4R07T324. A week later I called stating that the machine was making a loud sound on the spin. Makro shoved me onto Samsung to deal with the issue. After much anxiety, an inexperienced technician came to check the machine, and after numerous tormenting phone calls from Samsung I was told there was nothing wrong with the machine. Makro never got involved to help with the query, yet the purchase was made with Makro. Now 4 months later, a qualified Samsung technician came through and found that the machine did have a fault and it was taken for fixing last Tuesday. A week later no feedback from Samsung so I called in to check. I was then informed that the machine needed a new drum, new shocks and a back tub. Basically, I was sold a defective washing machine at the cost of a new machine. Still Makro stayed away from the problem. Zero customer Service. Should I be getting a full refund or a new machine?
