bsnl broadband complaint link url

hi guys I remember there was a URL where I posted a complain that my speed was still 2 mbps despite 4 mbps upgrade. Then they immediately fixed it .

now my internet is down since 2 days, it says PPP Server link down/failed not connected. But ADSL link is up and fine.

I want ot register a complaint and get this fixed, I live in bangalore btw. Anybody got any idea?

Thanks,
Akshay
