Not provided internet connectivity but still demanded monthly fees

I took Hathway's connection in Feb-March 2014 (in Wakad, Pune). Barring a month after it, I have not been getting proper connectivity. I have complained 20-30 times every month. I used to get 3-4 days of connectivity every month that too after so many complaints and phone calls. No resolution was provided to me by Hathway. Instead, they are asking me to pay for all these months. I didn't get a connectivity, what should I pay for? Does Hathway want to earn without providing service at all. Instead, I am demanding Rs 1000 which was taken by Hathway as installation charges as I never got the connectivity. I have all the complaint numbers and call recording with the customer care. I have raised it to the Nodal officer, appelate authority and to the Hathway helpdesk as well. No one is replying to my E-mails regarding the refund of installation charges. I am fed up complaining and feeling being harassed by Hathway.
