TV not working within 6 months

I bought a Hisense 55" E7K 4K Smart UHD QLED TV with Quantum Dot & Dolby Vision at Takealot on the 28 July 2024 and it was delivered on the 05th August 2024. It has been working well throughout. When I switched it on yesterday (12/12/2024), it is not switching on at all, it does not have a standby light, it is just blank/black. I called Takealot to log a return but they said I should talk to the supplier. Calling Hisense, the automatic response says they are not available today, not even saying when they will be back. I phoned their Rep in one of the stores that sells their products, he says they are probably closed for December holidays, my complaint will only be looked at in January 2025 and there is nothing he can do from his side. This means I won't be having a TV for the whole December month and who knows when in January. How can such a well-known brand not have standby people to respond to emergencies? This is the worst service ever, they do not deserve even the 1 star I gave them.
