Videocon Industries — led tv under warranty

Address:

Bangalore, Karnataka

Sir,
I bought a 40 inch videocon led tv in nov 2016. It is under 3 years warranty period. Suddenly it got faulty and totally out of function. I made a complaint on 04 jan 2017. My complaint number is jai[protected]. I made many calls to its service center and to customer care and
Sent many emails as well, but still my led tv neither repaired nor a new set is given to me if it is irreparable. Almost a period of two months is over but they are not a bit serious to resolve my complaint on calling its service center and customer care they always reply that the part is not being available required for repair.. How long a customer can suffer to get repaired his under warranty product. Kindly help me in this matter as soon as possible please.
Thanks
