Bajaj Finance — CMP mandate debit charges applied 3rd time

This is the 3rd time that mandate charges has been applied over my account if there is no ongoing transaction is going on with bajaj
I have not purchase any product recently why this charges has made over my account Because of loan you provide us and all our bank details its doesn't mean that when ever you want you can make online transaction. So i request with bajaj team not make such type of transaction Now i feel that bajaj finance is not secure for providing bank details.
request you to provide the refund ASAP
