Hisense Absolute Disgust in your Technician Mabuto

I logged a call for a technician to come out to look at my fridge, the bottom freezer keeps over freezing, the technician from Hisense by the name of Mabuto came out and did absolutely nothing but had an answer for everything i questioned him on, he stood in my kitchen and was defensive , eventually he said he had 7 other clients to attend to on the 22/12/2022. He insulted me and told me to buy a new fridge. 10minutes after he left , he closed the call with reference number *** and it says completed repair. He further made a note that my warranty was expired, which it is not. My daughter spent over R14k at hisense Game the Glen and this is the service we get from Hisense. Is this what we have come down to? The fridge is only 2 and half years old, i cannot express my absolute disappointment,
