Worst service ever

My fridge has been broken for the past three weeks. Hisense has been giving me the runaround. The technician only came last week, which was two weeks later, and said that the is a part that is not functioning and needs to be ordered. A week later which is today, they still haven't said anything, tried calling them, they say we have to wait another 7-14 days, the service is just bad.
