Airtel — Balance deductions without calls

Airtel is unnecessarily deducting balance from my account without making any calls .
It is deducting 90 rupees everytime and in transaction history showing call done to same number (my phone number itself)

Also the call center guys are not responding properly.
Airtel is a big cheater I have lost more than 500 rs without any reason and they do not have any justification.
Wherever I recharge and they see balance, they deduct it

Last deduction happened just now on 30 mar
And 8 mar of Rs 90

Also they do not show any transactions in the app.and balance keep on reducing

Pls resolve this.this is highly irritating.
