You try contacting these people for connection

Personal experience -
You try contacting these people for connection — they will hardly revert back to you — they will run from you as they own you some money. Leave aside small cities, I tried this personally in PUNE.
There are no direct numbers to enquire — call centers numbers will suck your money keeping you in queue for hours.
Shoot an email to them and forget it… you will definitely receive the reply in 2 - 4 months.
Websites hosted on server with Biggest and reputed datacenters like RACKSPACE won’t resolve. They won’t open up. Normal layman websurfer will think that website is down or not present — but infact DNS servers of Tata are troublesome and hence website display page not found error though it is very much present.
I am suffering this problem since more than one year… they couldn’t resolve this despite several attempts.
Behaviour and responce of these people is like Government Babu working - egoist - slow - deaf ear.
I am waiting for the day when war between ISP’s will start for business….. these guys will suffer then.
One competent rival for them is Reliance currently and it is surely going to hit them hard.
Every big company starting a new thing in India always tries to suck at best instead of give away anything for the benefit of citizens.
