Redmi — To providing Solution of issue for Tv which is in warranty

I am compaliting about my Redmi TV (32 inch) not turning off by remote as well from switch in Tv. So, I have contacting Mi for same since two last two months but they are not providing any solution instead it gives time like, they will visit us within 5-8days and one technician came at our home but he is unable to solve issue. So i have re-complaint about it but still they not providing any valid input just giving time and after that if no one give solution and I contact again in Mi they again extend the date. Every time they extending time. Not giving any Solution even My Tv is in warranty.
