Spoilt TV barely 6 months after purchase

I am highly disappointed with the service I've received thus far. I bought a 55" Smart TV in June 2023 from Makro and it suddenly lost its volume then packed up totally in January. A technician came to inspect it on the 22nd of January and I never got a feedback up until I called and was told only repairs can be carried and I can not get a refund or an exchange for a bately 6 months television. I find it rather unfair with the way cases are handled like money wasn't spent to buy these gadgets. There is total lack of communication from hisense.
