Poor performance of Samsung tv model no.UA50J5570 50" LED TV

I BOUGHT A SAMSUNG 50" LED TV UA 505570 in NOV 2015. THE TV IS A NEW MODEL LAUNCHED NEAR DIWALI IN 2015. IT HAS DEFECTIVE HDMI PORTS WHICH REQUIRE REPLACEMENT OF MOTHERBOARD. THE CO. REFUSES TO REPLACE THE TV WITH SUCH A MAJOR FAULT WHICH INDICATES VERY POOR QUALITY CONTROL. SAME WAS PALMED TO A CUSTOMER LIKE ME WHO BELIEVED WRONGLY IN THE SAMSUNG BRAND. CAUTION TO ALL. NOW PROVEN. DONT BUY SAMSUNG PRODUCTS AND WASTE YOUR HARD EARNED MONEY AS THE CO. IS IMMUNE TO YOUR GENUINE CONCERNS.MY LATEST COMPLAINT REF IS 3700779782 of Jun 2016 end WHICH REMAINS UNRESOLVED
