TM are reputable for not fixing issues despite you lodge report with MCMC. They could just let the matter stuck for few months to a year until their infra is up. Judging from the look of it, the infra might be temporary a backup solution. They refuse to answer the question because the backend is awaiting installation until further instruction from their HQ. They will not answer your email or bother replying even you bombard their support mail. They'll only tell you the truth if you walk into the tm center with a spanner. But take note though, it's only the truth that they have no solution. And in the end, they'll make you wait. Trust me, whatever bullshit they say about complaining to mcmc are all useless. The complaints go up to mcmc, chances are that mcmc will just read the email and ask tm "kindly" what happen. MCMC will not push on the matter to settle. They'll just keep quiet . TM will just respond to you and probably fool around with some silly questions like check modem, check cable and what model you using.
TM service attitude has never changes. Despite Gobind Singh vows to improve our internet quality, the minute he says he's happy with the performance and step off, the same old TM quality came back up.

Under my understanding, TM still part of government property. MCMC is also government body.  Will you slap your own mouth if you're speaking foul language ? Unless one day TM is privatize which is impossible.
