Indian Railway Catering & Tourism Corporation [IRCTC] — IRCTC Refund not credited to my bank account

Dear Sir
I have booked a ticket on IRCTC having PNR [protected] and paid by bhim upi. I cancelled this ticket on 29 April and IRCTC refunded the amount with the same payment gateway but no amount has credited to my bank account till date.
I also mailed to IRCTC, they confirmed me that they already refunded the same and suggest me to contact my banker for refund and after that i visited my branch but they are unable to help me then i also contacted punjab national bank customer care several time and also discussed to the customer care representative over phone but till date i am not getting any fruitful response from them/pnb. Irctc furnished me the below mentioned transaction refund details..
