Broken Microwave Hisense RSA not replying to mails and calls

I purchased a Hisense microwave from Takealot, and it stopped working in less than 3 months. I followed the correct process and contacted Hisense first, using their official support email ***. I sent multiple emails and received no response whatsoever. I also tried calling Hisense several times, and the calls either cut off, go unanswered, or I am disconnected. Their customer service is completely unreachable. Only after failing to get any help from Hisense did I contact Takealot. Despite the product still being well within its warranty period, Takealot refused to assist and simply referred me back to Hisense — even after I clearly explained that Hisense is not responding at all. At this point, I have a microwave that failed within 3 months, no support from Hisense, and no willingness from Takealot to honour the warranty or assist a customer. I am requesting the following:

Immediate action from Hisense to repair or replace the faulty microwave. Takealot to take responsibility instead of redirecting customers to a supplier that is not providing support. A prompt and clear resolution, as all normal support channels have failed.

This situation is unacceptable for both brands, and I expect urgent intervention.
