Substandard Smart TV from Hi-sense and appalling service from Makro Crown Mines

I bought a 50'' Hisense TV on the 28th of December 2019 from Makro Crown Mines, Johannesburg. On the 25th of April 2020 it just went off while we were watching. This means that the TV was less than 6 months old! I emailed Hisense according to their warranty document and i never got a response. I took the TV to Makro and the customer service lady rudely dismissed me saying Makro doesn't handle Hisense repairs and i had to call them myself for repairs. I immediately emailed Hisense again and made a followup phone call. I was told that they had received my email and they asked for my phone number which i gave. I was also told a technician would get in touch to arrange for repairs. It's been more than a week and i haven't heard anything from Hisense. My number seems to be blocked now as ever since i confirmed my cellphone number with Hisense, their number is ''unavailable'' . Makro wont help either! I now believe that Makro and Hisense are running some kind of ****. They are in a partnership to ***** people's hard earned money by selling defective products. I don't understand their unwillingness to help when i spent my hard earned cash on an obviously broken appliance. The service is appalling to say the least!

I will never buy anything else from Makro or Hisense products from any other shop.
