Bajaj Finserv — CMP Mandate debit Bajaj finance limited

I had taken two loan in Bajaj finserve . Those 2 loans were completed in August 2020. After that they charged 295 Rs consecutively for 4 TIMES as Mandate fail charge txn with some dates. So totally they charged 1180 RS.

Regarding this I enquired with Bajaj finserve. They said your amount was deducted due to late payment of Emi dues.

But I knew I made late payment one or two dues .. But they charged 4 times..

Anyhow, I left that matter..
After all dues completed in August 2020. Now they charged 850 Rs as CMP MANDATE DEBIT BAJAJ FINANCE LTD in November

I don't know why they are taking money frequently in my bank account.

Sofar I am not using that account for any transactions. My mother get 1000 Rs monthly from government as widow pension. But they are looting all the money in the bank. Totally for three months my mother got 3000 as pension. But, when I calculated we got only 970 Rs .

I don't know whether this amount will remain in account.

I request the appropriate person to resolve the issue.
Thanks
