Requesting help about broadband services & laws for consumer

I must congratulate the team of experts for being part of such very useful initiative. Thanks for all the efforts.

I have couple of concerns/quires with me:

1. I have taken services from Reliance Broadband. Due to poor service, I have posted email

to stopping all the services to official reliance customer care email address broadband@relianceada.com. This was 17 Oct 2009 then after 1 month they replied that they need to have cancellation request & asked me to revert back, if I want to still cancel services.

I did reply to cancel services & asked to stop all the billing respectively [Q: can it be considered official closure request for services?] But it never happened.

Now the problem is they sent me the bill for additional month & as time is getting passed they are adding recurring cost in pending bill. for now my account is deactive due to non payment.  Now I understand that, I should have tracked the termination request first place.

But still, I am not finding it worth giving away the money for their mistakes & inadequate services.

I would like to know your expert views about the problem, what are the best possible solutions?

2. Also what all information can help me, if I need to get help from consumer forum/court in this matter for?

a.       How to register a compliant in consumer forum in pune location?

b.       Can I really achieve anything by registering complaint against big company?  

Thanks
