Airtel Broadband connection
Cannot use Gmail, Facebook and few other sites and very bad response from customer care executives

I am using Airtel broadband connection from past a year and there are too many problems with broadband internet connections, customer care executives responses and billing problems.. No use of calling up customer care number because of their negligence. kindly make your customer care executives to call on 8884344682 at least then i would get an opportunity to get out of the problems faced in broadband connection.
