Bad customer service from Head office no help received

I bought one Hisense 50" Smart TV at House and Home, Newcastle on Saturday, 3rd December 2022. I chose the one I wanted to buy from the stock available, but they did not want to give me that one. They gave me the front one which they obviously knew was faulty. They most definitely did not test it before delivery. They only let me sign the papers.

The TV stood for a few days in the box, waiting for my electrician to install it. When he switched it on, he immediately noticed lines on the screen. I immediately took the TV back .The person who tested the tv instantly showed where the fault was .It was like they knew this was the defective one. 11 December 2022. That was 8 days after I bought the TV and they refused to replace it because it was 8 days and not seven. When I went there later that week, I was told that they are not going to replace it, nor are they going to repair it for me.

My appeal to you, please do something about it. I am just a retired teacher with half a teacher's pension.
