Hi-Sense appliances do not work, and provide the worst after sales serviced

I have bought a hisense fridge a year ago, and the fridge has stopped working. Hisense via their contact centre were contacted for a repair, as the fridge is still under warranty. A technician was sent that attempted to fix the fridge, however the fixes did not last for a week, as the fridge has stopped working again. The case was reported again 5 days ago, and still to have fridge fixed. Firstly I am disappointed that a year old fridge has stopped working (This is the first fridge I have bought that could not last for more 6 years), and secondly, it seems there is no urgency on hisense to fix the fridge, which has grocery that would probably or is probably spoiled.
