Horrible customer service and make empty promises

I logged a complaint with Hisense regading my fridge. They send a gentleman in lockdown only to be told nothing is wrong with the fridge. I complained about the gentleman who came to look at the fridge he demanded sanitizer when he walked into my house and informed the manager, they should give their staff hand sanitizer because he is supposed to disinfect before entering a customers premises and again upon leaving. On the 16/7/2020 Inwas told by complaints manager they will look at replacing the hinges.... till today 21/10/2020 still no one came to replace the hinges. I complained again to the complaints manager then asked if he can arrange for a senior technician to come and have a look. I rep**** immediately on the 29/9/2020. I haven’t heard from him again. This is horrible customer service. I will never ever buy Hisense again!! The fridge has rusted hinges (they cant tell me why!! And the unit is over freezing) The unit is still within its warranty period but looks like they are purposefully delaying this to not replace the unit.
