Aircel India Cheating Customers with False Promises New Delhi, Internet

I had purchased a SIM No. 8285318375 from the Aircel counter at New Delhi International Airport on 15 June 2012 for Rs.3000 with a view to use the same for Internet browsing during my stay in India. I was categorically informed by the sales personnel that this SIM would be functional all over India except in J & K. It did work in Delhi even though the speed was abysmally slow. However, it stopped functioning completely once I left Delhi. I approached the Aircel office in Jabalpur (MP), my next destination, where the personnel informed me that this SIM would not work in the state of MP and was limited to a few states only. This is in contradiction to what I was told while purchasing the SIM. I am an Non Resident Indian and feel that I have been cheated. Complaints on the company website resulted in nothing more than automated replies of acknowledgment.I strongly advice any visitors to India to avoid purchasing an Internet connection from this company and stick to bigger names like Airtel or Vodafone. Unfortunately for me, I could not locate any other service providers at the airport.
