Airtel — broadband speed cheat

Address:

New Delhi, Delhi, 110075

As on the airtel website, the promised speed of broadband plan of 899rupees is 40mbps, and I am receiving speed of 16mbps. I have complained to them regarding this issue but everytime I complain them, they say "There is still no technology in my area". I don't get this I live in Dwarka which is a posh area and I am sure there might be a huge consumer base of Airtel Broadband here. They just don't want to provide the service. I request you to atleast confirm a date of when that "Technology" would be available.
