a few days back i was at my cousin's place. my cousin was facing some problems with mtnl internet so she told her dad about it who works in the army .. he got somebody to 'write' a complaint and gave it to mtnl office (i do not know addressed to who) but when i was there an engineer from mtnl showed up who i can honestly say was the most knowledgeable guy related to mtnl i have ever met. he knew about snr margins and everything and also told me that night 2mbps plan would also be coming to delhi he came from canaught place to dwarka just because the complaint had been made in writing. He did get the wiring sorted out at my cousin's place the next day and also got the modem replaced (with a 4 port one because my cousin uses a laptop too)
