Pathetic service after purchasing a Samsung microwave that stopped working after 5 months of light use

This must be the most pathetic online support "service" ever I purchased a Samsung microwave from Takealot, which stopped working after 5 months of light use. The Takealot policy is to process warranty claims directly with Samsung (which is 24 months), I've registered the product on my Samsung account and requested a call back. After which I received an emails telling me to test my plug point... why would I have contacted Samsung support if the problem was with my power??? And why did I receive an email response after requesting a call back??? Next I tried the online chat, and chatted to "Tebogo" who advised that I have to take the unit in to a repair center to assess the microwave to determine what caused the fault. The microwave stopped working while being used to warm up milk for 1 minute, now "Tebogo" wants to tell me that it was because of a power surge...he's not qualified to make this conclusion. My whole house is protected by a surge arrestor, and no other electronic devices are affected... All I wanted was to get details on what the next step is to get this microwave repaired under warranty, I'm not interested in "Tebogo's" opinion.
