Furious

I bought a hisense tv from game Shelly beach on the 20th of March . On the 22nd while watching Netflix it flickered and went off and never came on . We took it back to game and they sent it to you . I was told that have ordered the wrong part . How do you do that ?? How do you supply a defected tv to a store who then sold it to me . And I have been inconvenienced for this . You have been sitting with this tv for more day than me . How do I know that my tv will sent back. To me . I don’t care what the problem is as I know it was not negligence on my side : I want a brand new tv . Can this be treated with utmost importance . As I am very irate and upset customer .
