Hisense useless as appliance

I thought that Hisense was one of the strongest brands when it comes to making appliances but oh boy i was wrong. I bought a 55 smart tv from them and i was happy like no ones business but soon as i was out of game store with it it started giving me problems. First it did not want to log in to the internet using wifi then i thought better use the cable then it just took out sound and did not give a picture then i took it to get fixed last year and they kept it for more than 3months. I had to fight to get it back and now i wake up this morning the TV has done the same thing. My advice to anyone who is looking to buy a good brand on appliances please don't buy Hisense cause you will end up spending more on fixing the dem thing. That is the reason it is cheaper that its competitors, my R10 000 gone.
