Makro sold me a broken TV

I purchased a 55inch Samsung TV from makro. The TV was tested in store and then dropped back into the box. The shop assistant handled the TV without much care. When I got home and plugged the TV in, there was a black thermal crack running across the entire width of the screen. The following day I returned the TV to Makro and they refused to take responsibility for replacing or refunding me for the TV. After many months of correspondence they still refuse to help me with this problem, instead blaming me for damaging the TV, which is not possible! Their customer service is terrible and I wish that I had never bought anything from them! I would advise all future shoppers to buy their goods elsewhere!
