Hisense TV 58 Inch 4k - The worst

I bought a TV (58Inch) in 2020 Oct in 2022 the TV just stopped working (when you switch it on the red light flickers about 5 times) and we returned it to the store and they had to take in with Hisense repairs. Ever since then we just know every 4months the TV has to be taken in for the same issue and what Hisense is saying is that they can’t do anything and we should have returned the TV within 6months if we were not happy??? Tell me how when the TV started with this issues after a year. How are they fixing the same thing 3 times in a row clearly for me that is a sign that the is an issue with the product.. Still have not gotten help till this day
