"Faulty Hisense 50" E7K 4K Smart UHD QLED TV - Lack of Assistance from Takealot

I purchased a Hisense 50" E7K 4K Smart UHD QLED TV with Quantum Dot & Dolby Vision on October 28th, 2023, and received delivery on October 30th. However, on Friday, November 24th, the screen started intermittently going black while the sound remained. Additionally, the screen began fluctuating from dull to bright.

After reporting these issues via email to Takealot on 27/11, I was instructed to log a return. But, when attempting to do so through the app, I was informed that returning the TV was not possible. I contacted Takealot again to explain this situation. It was then promised that the matter would be escalated to the Supplier Warranty Team for further assistance, which was supposedly done on November 28th, 2023.

However, as of Tuesday, December 5th, 2023, I haven't received any feedback, and the problem with the TV persists and is worsening.
