what's the point of buying hisense

I bought a hisense fridge 26 October 2014. It started giving me problems last year December. I requested for a technician but the technician never showed up.24 February master care calledme to confirm my job number and that the technician will come over that day but still no one showed up. Today I call master care and am told that I can not be assisted because the technician is sick. Do they only have one technician around gauteng? Am fed up of waiting and I want this fridge out of my place. I can not wait anylonger
