Disgusted

I bought a Hisense dishwasher from Game in July 2018, this dishwasher has now stopped working. A Hisense technician came to repair it after I fought and shouted for them to come to my house. The dishwasher only worked for 2 minutes and immediately after I called the technician, who said I was lying the dishwasher is working properly and I shouldnt tell him about it. So strange that the customer is treated this way and wit such disrespect. I am sitting with a dishwasher which is not working and I have paid over R5000 and Hisense DOESNT CARE.
