Hisense complaint: Ripped off

This tv 55R6E3 or any other Hisense. My mom bought 3 at the same time about 3 years ago. All the TV’s went to different address because they were gift’s. So a year and half the first tv went out all trouble shooting steps didn’t fix it After about 8 more months 2nd tv went out same issue just turning on and off and only can see Hisense logo for a second then back off. So now the 3rd one is broke now and had the same issue on them all. I reached out to Hisense about it again. The agent said its not the TV’s its your power. I told them that’s not it unless all three of our houses would have power issues. Follow the tech advice to try and have it reset pushing reset on the back and nothing help. I then asked about what he told to try and he just stop replying to me. After waiting 5 minutes to see he would come back and nope so I closed it. I got a message from transcript I asked for. and didn’t reply back for 13 minutes. So I will NOT ever buy anything again from Hisense
I honestly believe they are sending updates to the Tv’s that cause this issue. I have read a lot of complaints that people are having same issue just goes on and off won’t load anything. Hisense screen goes on and off. I’m working on hiring a attorney and will have thousands of people to join me on this. I have spoke to a attorney that interest in taking this case. I will save all pages I meet people on with same issue.
