Passing the buck

I purchased a Hisense fridge in May 2024, the unit was no longer keeping items cold. Reached out to Takealot who stated I need to reach out to Hisense directly - a little irritating as I do not buy from Hisense… reached out to Hisense who took 3 days to get a representative to come to site, it seems a new fridge was sold to me as there as a “line tap” in the main copper coil feeding the compressor. So Hisense voided the guarantee - I purchased a new fridge and went through the correct channels however 3 weeks later I have no resolution!! Today I’ve been k formed that Hisense shipped the product direct to me to Takealot is not taking responsibility. POOR SHOW!!
