Hisense product and service

Bought Hisense tv in 2019. 2021 the screen is blank. Called Hisense and the tech came to check and advised that they need to order parts. Few days later it was confirmed via sms "categorized as (completed repair)... I called to check what that means and was told that there is a back order on the parts and that was indicated in the Sevice Repair Job Card and that makro would know that it means credit on the tv, all that I needed to do was to take the doc to Makro to get another TV. I decided to call makro who advised that Hisense was supposed to send them some docs to cinfirm. I sent them the job card and was told to go to makro to collect the tv. Before I left I decided to call makro to prepare them. Makro told me that they need to get a "credit confirmation" doc from Hisense. I decided to have a conference call between myself, makro and Hisense. Hisense consultant confirmed that he will arrange with their credit dept to send makro the form. When I made another follow on the same day with Hisense credit dept, the lady said she must first confirm if the parts are still on back order or not. I had to explain the same story that I have to more than 2 people in Hisense. I asked to speak to the same consultant that promised to speak to their credit department and hey, he was too busy. The service from this place is horrible. I will never ever buy Hisense products, one for that service and two for their poor quality product. I have had TVs running for years and this did not even last for 3 years!!!!!!
