Airtel — wrong deduction and giving wrong information.

Address:

Agra, Uttar Pradesh

I am using airtel prepaid my phone no is [protected]. L have account balance 649 on date 31st august 2018 and my unlimited pack was valid till 31st aug 2018. I recharged my account with 448 on 1st september 2018at 12:10am. They deduct 422 rupees from my main account balence. On calling customer care one customer care executive said the deduction time is 10:22 pm 31st august 2018 but at that time my pack was active. Second customer care executive said the deduction time is 12:19 am of 1st september 2018 but at that time my pack was also active. I got a message from airtel that i used 10 mb data from my main balence. Then why they deduct 422 rupees from my main balence.
