Airtel — broadband connection not available in my area

I have always been told good things about airtel’s broadband services, but, to my dismay, it was told to me by the airtel executive that their services are not available in my area without any sort of inspection. He did not even inspect or come to my address and told me since it’s a government quarter the services are not available. There are several brands with broadband connection in my area then why is only airtel having a problem in installation? Poor customer service.
