Samsung NEVER AGAIN! - Worst service I ever had - So Disappointed

On the 29th of May 2018 I phoned Samsung Care, after my UA55J6300 Curve Smart TV stopped functioning the way it is supposed to. The Samsung website had instructions on what to do if your TV doesn't connect to WiFi anymore & the firmware update failed. I followed all these procedures which involved resetting the TV via the main menu. I reset the TV, it restarted & then I got a blank screen with audio... The audio plays in the background, but the screen is dead. After speaking to Samsung Care, they advised me that the TV is under warranty as it was purchased on 11 August 2016, and that they have given instruction to Pretoria Appliances & TV to come & service the TV on-site, as this is what is required. They told me the partner will contact me to make arrangements, which have not happened and today we are heading for a week without communication. I tried phoning Pretoria Appliances & TV, which either rings the whole time, or is in use all the time. I have now had enough! From having an entire home with just Samsung devices , I think I should just rather move to someone else. My whole life I supported Samsung, now that I need support, I get sent to some third class repairman who cannot even contact a support client - And then they have the decency to call themselves an authorized repair center... If that is the quality of partners you use, I would recommend having a good look at your support strategy
