Reliance Broadband — Billed for Internet Usage when the Internet was not working

My Internet stopped working since 5th July 2008 . Till today, 1 August 2008, there has been no effort on the part of the company to restore my Internet Connection.
I have registered 4 complaints with the customer care department . Someone comes from some third party office, checks my connection, tells me that they will do something and goes away. Then they close the request from their end.

I have been billed for Internet Usage from 23 June 2008 to 23 July 2008, whereas the Internet is still not working since 5 July 2008.

When i raised a complaint for the bill, they closed the complaint saying that the issue was resolved within the SLA periods, whereas the fact is that my Internet is still not working.
