HISENSE 55 Inch TV

I had my HISENSE 55inch TV repaired just over a year ago. I bought the TV in 2017 for R11000. Surely I can't sit with the same problem if new parts were installed. Either the workmanship is poor or HISENSE products are of poor quality that does not last. I can't be expected to buy a new TV every 4 years of R11000. The last time it went in for repairs I had to follow up all the time and no one answered the calls. When I finally decided to go in to Motagu Garderns myself, the TV was ready for alomost a week. Pathetic Service as well.
