Search for airtel broadband on Google or just click the link airtel broadband - Google Search.
You will come across at least 4 sites - airtel-broadband.com, airtelworld.com, airteltelephone.com and airtelbroadband.in. I don't know why an ISP needs so many sites with so little information. I am trying to find out a best broadband usage plan and none of the sites have this information. Some of them just do not respond and some show jsp / jrun errors.
It seems too many people outsourced the web site creation for airtel. Here is a company that doesn't care what their web presence is. I guess their sleek commercials give them the confidence that they can run a business successfully with bad customer service and support.
