I am Surja bahadur Chhetri. I had applied for ibps rrb po 2023 and for the same i had done payment of rs 850 for it through Google pay UPI. The payment is showing successful and the amount is deducted from my bank account but the same is not reflected in my application form. There is no acknowledgement receipt for the payment in application form. Therefore I request to refund the amount in my bank account.
