Hisense SA does not honour their warranty

Where do i begin... I purchased a fridge that is still under warranty, a technician came to assess and said the fridge has an internal leak amd must be replaced, hisense sa REFUSES to replace the fridge as the midel is no longer available. They want to reimburse what we paid two years ago which comes nowhere near replacing the unit with a similar spec. Its ********* and incorrect for us to replace a defective product that was under warranty at our cost. The unit should have been replaced with a similar spec out of current models. We have called the callcentre numerous times and requested to speak to management but but a customer service person by the name of Kevin refuses to put us through. This is not customer care ethics as we have purchased many items and all still under their warranty so where does that leave us.. It is not our fault that the fridge has an internal leak the product was defective why should customers have to suffer the consequences of an inferior product. Hisense Sa we do not want a voucher we want the item replaced. It is not our fault if thr product cannot be repaired. We purchased hisense mainly because of the warranty now we are left with this. Extremely disappointing. I will NEVER support this brand again i will also advise evwry family or friend to not support the brand either
