Airtel — Double payment of recharge amount ,mob no [protected]

Address:

MAYUR ABASAN ,BLOCK C , STATION ROAD , PO NABAGRAM , DT HOOGHLY.,

On 15.01.2021 while recharging of Rs 598/ on prepaid mobile no [protected] through debit card, it said payment unsuccessful . Once again I tried and same thing happened, though in both cases my account was debited .Since that was the last day of validity I recharged from local shop . Afterwards it was found that payment was accepted and they have arranged to make one refund, which is yet to be received .
So assuming that one amount will be refunded, the situation is that I have made one extra recharge which is done from outside .
So I request you to either refund or keep that as advance payment and to make it effective as soon as the next recharge falls due
Thank you .
