Some indian paypal account holders cannot update the IFSC code for their bank account and have not received payment

Due to the bank mergers of government owned banks to Punjab National bank, the IFSC codes for some bank accounts have changed
Some paypal account holders are finding that they cannot change the IFSC code for their account.
They also cannot add a new bank account to their paypal account with the correct IFSC code
So the payment is going to the old IFSC code and disappearing since April 1, 2021
The bank is claiming that the amount will go back to the sender, yet paypal is not showing the returned balance, so that the amount can be transferred into another existing bank account.
