Hisense Fridge- poor service delivery and response

I bought a Hisense fridge at Makro on the 28/03/2021. About a month ago the freezer stopped working. I logged a call through Makro and a Hisense technician was sent out and fixed fridge by regassing it. 2 days later the freezer and fridge stops working. I log another call through Makro and have since escalated the call 3 times, with no response or acknowledgement from Hisense or Makro as to when the fridge will be fixed or replaced. it has been 2 weeks now, with no fridge. I have logged a complaint with Makro and received an auto response, no follow up. I have now logged a call with Hisense directly with poor service from the agent to say the least. I now need to wait Another 3 working days for someone to come out and assist and a new job card has had to be created.
