Warranty TV need replacement

I Sifiso Mlangeni bought a Hisense 55inch Smart Television at Hi-Fi Corporation dated 27/09/2019 and it has a 4 years warranty. On the 24 March 2022 my TV switched On but no visiul screning appearence. And i took it to HiFi Corporation the following day since its still under Hisense Warranty. The 2 April 2022 i inquired about my TV its status but i was told the technician will look in to it. Till now no respond about the TV.. With all days passed by without my TV, i FEEL Hifi Corporation does not have customer care especially if your BLACK. if i was another race ,the tv would have been replace with a new one.My take now is i don't want anything to do with the repaired TV but i need it REPLACED with the NEW one as Hisense company have warranty towards its product .The TV is still under the warranty bracket. I RECOMMEND PEOPLE SHOULD REFRAIME BUYING PRODUCTS AT HIFI
