My Hisense Nightmare

Our 65 inch Hisense TV, not older than 2 years, developed white spots on the screen. As the TV was still under warranty we contacted Hisense to repair the TV. We thought this went well as they came and collected the TV within a week. Another week went by and they contacted me to deliver the 'repaired' TV. When the TV arrived the whole side of the screen was shattered. I contacted Hisense about the screen and for three weeks they didn't respond. I decided to call them and eventually they sent me an email saying the TV will be inspected/repair. I haven't heard anything from then since. I have sent 20 emails without any response. I can't say this is the worse customer service I have experienced as there are no customer service to experience at Hisense.
