Airtel for the month of February charged me additional Rs149 for International roaming. On my Airtel no such booster shows to be active. I have not travelled abroad in the last 5 years. Even my airtel application does not show any such boosters active. Even in my previous bill they charged me for this amount for international roaming. If someone does not check the bills they would keep on charging customers through this. Why shouldn't this be treated as financial fraud.
