Bad experience with tv

Last year march 03 I bought a tv jvc 140cm. I was happy bt my happiness didn't last because December my tv started to have problems January I took it a shop and promise to fix it. I collected its after a whole month I was glad I got it back after 9days its completely went off. They said I must bring its back with my own expense so they can fix it. I not sure its will last after this. I dnt trust it. And I demand they give me something to watch n this time bt they brush me off. Help get my tv back please
