Hisense Tv it’s a bad brand

In May 2021 my TV could not switch on and took it for repairs and it was acknowledged, since the TV was under warranty the TV was repaired in within 3 weeks. Today 08/07/2021 the same problem has now occurred. As a customer I had faith in this brand but now its letting me down, I cannot fix the TV every 2 months because if the TV breaks out of warranty will be very costly to me. We are in the midst of a pandemic, television is a source of information please attend to this query to regain our trust in the brand. Resolution I need the TV to be replaced and the warranty to be extended or be refund as I lost so much faith in the brand which trusted with my money. I hope we will find a common ground to resolve this matter as this is inconveniencing me and my family.
