Canara Bank — amount refunded but not reflected in my account

Address:

Palakkad, Kerala, 678009

Sir,
I have booked a flight ticket from bhuvaneswar to bangalore through paytm on flight air asia. But the flight was cancelled by authority due to cyclone fani on bhuvaneswar. We contacted paytm and they initiated complete refund and they gave a transaction i'd for 3 passengers. The email screenshot is attached below. But it's been 10 days and no amount is reflected on the account. No response from bank branch too. The account branch is iit palakkad. Please do something needful
