Hisense sells faulty products

Poor Products being sold to consumers. I purchased a 55'' TV which I have had for just over a year , the TV has stopped working now on 3 occasions in the last year. Each time it gets repaired which take 3 weeks , I get it back and 1 week later it stops working again. Clearly a faulty product and I get told that they can repair it again . Is it worth it spending so much money on products which are faulty, I advise against it . I get no feedback on emails and complaints sent .
