Airtel — International roaming pack billed without our consent

Hi..

My wife's name is Indu and we live in Faridabad, Haryana. Last month, we had to travel to Dubai for some personal work and we took flight on 25 December. We did not require any international roaming package from Airtel and we did not ask for it too. But, when my wife received her December bill, we were shocked to see that Airtel has imposed a per day iUAE roaming package of 649/- Rs. on us and they have also charged for other international call and messages. Since than, I have sent our complaint via their twitter and Airtel app, but have not received any revert.

Please help us on this issue.

Our bill no is [protected].

Airtel people can contact us via our registered e mail.

Thanks
Ashish
