Airtel — postpaid international roaming billing-[protected]

Address:

Khordha, Odisha, 751010

I am on international roaming effective 12 th august 2017.
However, i notice from bill dated 24th aug that i was billed the amount of rs 3999 which is for a month. I have also been billed the same amount for ir in bill dated 24th sept, 2017.
Since i used ir for only about 15 days in the billing cycle 24th july to 23 aug, the billed amount should have been for half the amount.
Please review and reconcile and convey to me by email, earliest.
