I have booked a railway ticket but the transaction failed due to network failure and money was deducted. I got refund msg from irctc, that 'an amount of rs 838.68 deducted against irctc txn id [protected]on 03-oct-2019 will be refunded as your ticket could not be booked / service not rendered. But hdfc haven't credited it in my account, till now, and one same day i received another msg from irctc that 'ur transaction on hdfc bank debit/atm card ending * for rs. 838.68 has been credited/reversed by irctc12027 on[protected]:16:51:15. But till now no msg from the bank i have received also i have cross-checked it with atm. I want support from the bank.
