SAMSUNG NONE EXISTANT SERVICE.

My 58 inch SAMSUNG UHD TV stopped working 2 weeks ago. This TV is 15 months old and still in the warrantee period. MAKRO Alberton and I have repeatedly contacted SAMSUNG still nothing has been done about it. I cannot believe that a company like SAMSUNG has such terrible service. Are they waiting for the warrantee to expire or are they not interested in any form of customer service? I suggested to the MAKRO consultant that they replace the TV and then take it up with SAMSUNG because I bought it from them. He advised that nothing can be done until SAMSUNG look at the TV which is as dead as a doornail. I will never buy a SAMSUNG product again if this is typical of their customer service or should I say, lack of service.
