Punjab National Bank [PNB] — not getting my refund

This is rahul mehra i have done refund of 22000 from paytm to pnb account no [protected]
At the date of 14 june 2018 and its about 9 days now i contacted to the paytm they said we have successfully send money to the pnb and gave a refrence no to me 30001081668165229296306
But customer service is saying they can file nothing like charge dispute and can only check if money came to your account or not.
Same behaviour by branch also.
