Poor Customer Service

I purchased a samsung double door mirror fridge. The fridge starts tripping my power at home. Informed Samsung and they refer me to their local agents TM ELECTRONICS to inspect and repair. technician pitches up and is clueless refuses to wait for load shedding to end. Tell us that it is the heater and thermostat at fault. We tell him we suspect its the compressor on fridge. Technician rudely tells us he knows his job. Nonetheless we pay for a new heater, thermostat , callout fees and labour. A week later the parts replaced. Technician then tells us that it was the compressor at fault. I was left in shock by the sheer incompetence. Now still battling 5 weeks later with the warranty issue on the fridge and getting a refund for the incorrect parts replaced by the Samsung Agents. Being a loyal Samsung customer I am in shock at the pathetic customer service. There is no accountability and their agent proudly tells us we can do whatever we want to about the poor service.
