Punjab National Bank [PNB] — pnb - refund not processed by pnb bank

Address:

Bhawanigarh, Sangrur, Punjab, 148026

Pnb has not yet credited and processed refund into my bank account which was being processed by paytm on 19 september 2019. I have also shared the bankreference no. Which is 30001092639251119741693 then also they are unable to locate the amount and telling me everytime to check with paytm. Had paytm not credited the amount how would they have given me the reference no which is also generated in case of transaction. Request to kindly refund the money into my bnk account...
