SAMSUNG - UE50KU6020 Smart 4k Ultra HD HDR 50" LED TV - D.O.A! I bought a SAMSUNG - UE50KU6020 Smart 4k Ultra HD HDR 50" LED TV from Currys on 21/11/2016 which suffered from multiple issues; the wi-fi disconnected frequently, the screen colours were extremely poor, and there was a black strip intermittently flashing on the screen. This was eventually replaced by Curry's but only after much resilience. The replacement however also had wi-fi issues and a black intermittent strip down the screen. Curry's declared this was now the manufacturers (Samsung's) responsibility and said they could not help me further. After dealing with Samsung over the following year; running through endless over the phone tests, calls, delayed emails, a failed screen replacement and a number of missed engineer appointments I am left no better off than where I started. I have experienced complete incompetency at all levels from both companies in the handling of my case and vow to never use either again.
