Allahabad Bank — my refund is not coming in my account

I book train tickets in Paytm app. And I cancelled it from my Paytm app. It has been 5 days since I cancelled the tickets. But my refund is not coming. I approached the Paytm customer care but they are telling that the bank is responsible. They gave me the refund ID and asked me to ask the bank. The refund status ID is[protected] 529.

Kindly please take necessary action.
And please I want my money back.

Thank you
