Institute Of Banking Personnel Selection [Ibps] — Transaction failed but amount has been deducted from my bank account

On 26th of September 2021, I did a fee payment of Rs. 850/- to complete the registration for the IBPS Examination, after the payment got deducted from my account it was shown that some error occured and is again asking for payment of the same amount but the old transaction amount has not been reversed to my bank account.

I hereby, kindly request you to reverse the payment of Rs. 850/- which I have done for the IBPS Examination registration through online.
