Sony India — sonyliv not working since 4 months

Address:

New Delhi, Delhi, 110035

I have sony bravia led tv and sony is installed in it but since june its not working. When i open the app and plays something it plays only for two minutes and then it starts buffering that never ends. I am very exhausted with this. I have mailed more than 100 times to sonyliv and they have replied just 3-4 times, they asked me for some time but till yet it’s not solved. Four months is not a short period. The only option left with me is to get to the court. I request you to please help me with this issue.
