[Resolved]  BSNL - broadband — Useless broadband connection & service

Myself P Saha and I am lecturer in a Govt Unversity.
After 6 months of waiting I get the connection of broadband service (Phone no. [protected]) this month from my local telephone exchange (Nimta Telephone exchange). They connect it and then I get the ID, password also, but unfortunately till now the internet line is not working. When they connected the line, modem etc, they charge extra money etc for better service, but after that nobody come to see the matter. I also dont know what is the use of the helpline no, and the exchange phone number given in the list when this are either useless or nobody entertain the call. Whenever we try to contact the helpline no. given in the list, nobody receive the call. I tried again and again, but no result. One day they recieve it ans tell to call after 2 hrs, but after that nobody receive the call. After trying 2 days, they have received the call they told to contact local exchange, and local exchange told to contact to kmain exchange evert time. But they dont have any time to verify the matter of connection problem and to help us. Rather they misbehave with us whenever we try to call to main exchange. Is this is the service of BSNL and we have to pay monthly subscription of this useless type of service?
