Samsung products the worst

Bought 58"samsung smart tv at ok after 14 days it just started switching on & off we didnt know what to do so thought lets return it to ok furn when we got to the store the tv had the smallest scratch so we told them that it was absolutely fine when we took it from home which means it got a scratch on our way to the store which wouldnt have happened if the tv was working .im so disappointed as we are told that we have to pay 7000 for the screen and they wont fix the problem the tv had when we returned it and they saw what was happening with the tv and also at ok furniture for failing to assist for the tv knowing very well it was on display and had no box for us to return it with .
