Thomson Led Smart Tv — replacement under warranty

I had bought one thomson led smart tv 43" by your company. Invoice no fabsbs[protected]. There is problem in my tv and i sent mail to thomson they said to replace the tv but after one month there is no response by them. Right now it seems that they aren't interested to solve my problem. I thought flipkart is so big multinational e-company who take care of their customers that's why i bought tv through flipkart but now i think nothing to buy online.
