Airtel — excess charge on mobile recharge

Address:	560076
Website:	Airtel Payments Bank

My airtel payments account is linked to mobile number [protected]. On 17 sep 17, i recharged another airtel number [protected] for rs 247/- paying through my airtel payments bank account. However, the amount was deducted thrice from my account yhrough three successive transactions as per the details below.
First transaction on 17 sep 17 at 08:31 pm for amount rs 247.00 against transaction id [protected].
Second transaction on 17 sep 17 at 08:41 pm for amount rs 247.00 against transaction id [protected].
Third transaction on 17 sep 17 at 08:47 pm for amount rs 247.00 against transaction id [protected].
I have been making requests to the grievance officer (Gro) of airtel payments bank since then. Despite repeated attempts made by me, i have neither got the excess amount reimbursed nor the beneficiary number got the additional recharge. The issue is not about the amount but about ethics. I hope justice prevails and the excess charged amount gets back into my account.
