Customer service is non-existent

I ordered a Hisense 264L Bottom Freezer Fridge for my elderly mother on 21 January 2025 from Takealot. In the first week it was already showing signs of problems - which has now cropped up again. Items in the fridge become wet. The side is too hot to touch. The crisper is basically a water receptacle.

I mailed Hisense on the 27th of Jan 2026 and have been met with silence, other than a short reply about the reference number when I asked what's going on.

I can't imagine how customer service can be this bad. My mother is struggling with this fridge and I want it out of her house and my money refunded. I'll rather spend more and get something decent from a company that has a better level of customer service - which should be easy as the bar so far has been set extremely low.
