Airtel — postpaid bill overcharge rental

Address:

Pune, Maharashtra

I have recently changed my circle from chennai to pune.

And paid amount 491 for the last bill generated (Transaction id :[protected]
The bill generated was 780 but it was waived off and the amount i paid was 491 as i was charged for data where as i had data balance.

This month (10 dec to 10 jan) the bill generated is 707 rupees where as my post paid plan rental is 399. I want to know why i am being charged this much amount??

I have been reaching out to customer care from last week who is unable to provide me any solution and is bluntly providing me a time line of 24 hrs and 72 hrs even after which the issue is not resolved.

As spoken to one of their representative saritha parimar.
