Vijay Sales — tv display issue

Address:

Mumbai City, Maharashtra, 400042

We had bought videocon led tv from vijay sales (Bhandup) on 29th sep, 2016.
Last month i started facing issue with the display, post which we called vijay sales to complaint about the same. After almost 15 days of complaint some technician from vijay sales visited our house & said the display is gone & he will post the complaint to videocon & they will help. Its been now more than 15 days post the technician visit we havent heard from vihay sales nor videocon. I had visited vijay sales personally but no postive reponse. Since past 2 days i am calling their customer service number but still no response.
