Smart 3D tv

We purchased a smart 3d TV from Makro on the assurance that it was the better brand. Customer service was assured only to find out that 5 and a half months out of warranty the TV only flickered. We then tried to contact the store and were informed it should be taken up with the manufacturer LG. On further researched we found that the issues we experience is not uncommon for the model we brought. Lg now wants me to pay a courier charge and assessment fee. This was not discussed with me and now we sit with a R8500 TV which they LG will only repair at our cost when the problem is a manufacturing fault not just on our unit but numerous of that model. Our advice, do not buy products it last only as long as the warranty
