Questionable service when product is still under warranty

I bought a Hisense fridge from Game (still under warranty) and it stopped working. I lost all of my frozen goods and refrigerated food in the process as I was away for the weekend - everything went bad. Visited Game on Monday to report the problem and was reassured that it would be reported asap, which it was. Hisense (Heidedal, Bloemfontein) called the following Thursday to arrange a visit from the technician. I then cancelled all of my plans for the day to be present when they arrive. At 16:30 I phoned Hisense to find out when the tech will be there and he arrived at 17:00. Did not really do much to resolve the problem, left, and told me that they would come again on Monday. AGAIN I changed plans to be at home. No one came. Called first thing on Tuesday to find where the technician is - answered with a don't care attitude that they will "see" what's going on. It is a really bad situation seeing that I am 84 years old, cannot go out on my own daily for fresh food as I rely on other people to drive me and really need a fridge, not only for food, but also for medication and Hisense could not care any less.
