Lack of customer service and empathy

I bought a fridge 3 years ago and 8 days ago it stopped working. I contacted Hisense as it was still within the warranty period. They sent a technician 3 days later who reported that the fridge cannot be fixed. The agent from Hisense Veronica Ramutsindela seemingly does not care. She does not seem to understand the urgency. The phone numbers do not work. Management has approved a replacement but as the store I bought it from no longer exists she cannot provide a solution and has ignored my request for a managers number. Highly frustrating!
