Bajaj Finserv — EMI Card related deduction

My loan account number is 595CDDEK823425. The loan has been pre-closed remitting all the dues and charges. On December 4th 2020, my bank account was debited for rs.295 twice as a mandate fail txn charge.

Again debited money on the following dates:

14th June 2021- CMP Mandate debit rs.117
18th February 2021- Mandate fail chrg txn rs.295

I mailed the customer care and they said it has to be done from the bank's end. When I asked the bank, they said it should be from Bajaj.

They are deducting money whenever they want to. Please consider this at the earliest.
