Do they even have them anymore? I've been having a problem with high latency for the past 2 months in Chennai, and their first level customer care and so-called technical department has been of no help. In fact, one of them even tried to put the blame on me

I'd like to contact someone higher up, but mailing their nodal officer's id keeps giving me an error message from 121. Any ideas?
