TV under 2 years old does not switch on

Good day

I purchased a TV on the 10/07/2019 from takealot and app**** for an extended warranty. The TV is still under normal 2 year warranty and does not want to turn on for some reason. Model: 58A6100UW

I am not happy that a TV I spent so much money on doesn't even work after 21 months.

All TVs I purchase are Hisense, this is the first time I've experienced such issues and it's making me feel like I should change my brand when purchasing my next TV.

I'd like the below matter dealt with, with a sense or urgency please especially seeing that I am a loyal customer and brand ambassador for your company.
