Airtel — Airtel Xstream fiber broadband

Airtel Xtreme fiber internet broadband — I have tried everything with them. My internet doesnt work.I paid for 3 months. I got their connection around 2 months back. Out of the 60 days, the internet has been shut off for more than 40 days. I tried calling customer care, they promise to resolve the issue but nobody comes to rapair the connection. The service provider is horrible. I asked for a refund for which they refused. I asked them to atleast refund for a month of service which I have not used, they refused for that also. Now my only hope is the consumer court.
