Hisense didn't fix the issue while still under warranty.

Please can you assist me regarding the my Hisense LED TV 50N300UW. I have had endless issues. Especially with the picture quality that l have reported endless and told they it's NFF.This issue has gotten worse and if this was addressed s i time i doubt l would be having this nightmare and at this stage l regret ever getting a Hisense LED as l have not enjoyed using the product and also the service. As per Hisense they were so quick the TV is now out of warranty and cant assist. I have been reporting the issue while still under warranty and nothing was done.
