Bank Of Baroda — confirmation regarding payment refund in my account

Address: Bank Of Baroda , near munshipulliya Chauraha, Indira Nagar, Lucknow, Uttar Pradesh, 226016

I had booked a ticket from Paytm app on 01/06/2019 which got cancelled on the very same day due to some issue and I got message from Paytm regarding the payment refund on the that day itself but when I crosschecked it with my bank account after some days the money wasn't credited to my account . I contacted Paytm customer care no Several times and even visited bank for the same and Paytm customer care told me that the payment was already made successful from their side the same day but bank has not confirmed it yet. I even contacted the management team of Paytm and had series of mail exchanges concerning the complaint lodged with Paytm then I asked them to provide me the transaction ID for the payment processed and they even provided me that and had also asked me to file a official complaint with bank with chargeback form
