Bajaj Finserv — EMI Debited after Foreclosing the Loan

I had a Flexi loan 421TFTGN337571 for Rs. 5, 00, 000. My customer ID is 12698305. I have foreclosed it on 30/07/2021. But I have received message, that I have to maintain Rs. 7639 in my account balance for this loan account 421TFTGN337571 on 02/08/2021. Today(02/08/2021), my bank account was debited Rs. 7639. How could you debit money from me, for a loan I preclosed by paying extra Rs. 30.811. Isn't that enough.
