I am Nitin Jadhav & i have a prepaid connection of Airtel Mumbai no. 9892626229 & its life time card. Now i am in Gurgaon-Delhi & my Seam card is under roaming. The Last two days i cant received any incoming call as well as i cant do outgoing call also. Yesterday i try to refill some amount but that also not possible. I humbly request Airtel to kindly solve the problem.
