Bad quality and bad service

My Hisense fridge is under warranty, bought less than a year ago at Makro. The fridge started creating frost late November, I defrosted it, 2 weeks later it became so frozen that when I tried to open the shelf it broke. I went and reported it only for the technician to say my fridge is definitely not functioning correctly he will replace the thermostat but there’s nothing he can do about the shelf I must call Hisense. I called Hisense only to be told that there is nothing they can do about the shelves I have to pay to replace them my question was should the unit have been functioning the correct way my shelves would have still been intact they are team leader Zandile told me that there is nothing she can do so now I am stuck with a fridge that is 11 months old broken shells And creates so much frost that it cannot be opened I regret my decision to be associated with such a company that does not care about the quality of the product and the quality of their service.

Zandile told me that their voice of customer will contact me to hear me out and she will send me a reference number till today I have not heard anything from Hisense
