Worst of all. Quality as well as service both are unexpected and worst. Out of 10 i will prefer to give 1... No proper servicing. I launched service request for problem in our Koryo TV . One person came to see my problem , after that I’m Trying to contact again and again but no one receiving, if receiving sometimes they’re saying that they need more time. I am facing problem for more than 20 days. I have emailed them regarding all these problems but i get no solution.
