[Resolved]  Ixigo — refund of money of booking failed

I have done total 3 transactions through ixigo aap for booking train tickets on 17.01.2020 out of these 2 transactions showing booking failed but it already over 7 days that not refund amount of both failed transactions credit to my bank account.

Total disputed amount 1126.81x2=2253.62/- which should be credit to my account.

"refund against the trip id/pnr has already been initiated on[protected] and should reflect in your bank/wallet by[protected]. Refund breakup is as follows: refunded in bank/credit card/debit card: rs. 1126.81, refunded in phonepe refunded as ixigo money: rs. 0 refunded in other wallet: rs. 0 if you do not receive the refund on time, please contact the bank"

"you should have received the refund in your bank account by now. If you haven't received it yet, i request you to please raise a complaint with your bank's nodal officer for retrieval of funds as the refund was initiated from our end on 23 jan"

In this regards my question is that why should i contact with officer of the nodal bank for my refund amount...
