Bajaj Finserv — Fraud ecs debit

The ecs charges has been deducted from my citibank account with below details which i have never requested from bajaj. This is looking like a fraud done by either bajaj or keb hana bank. Can you please investigate and make sure the amount refunded to me back.

Note: i have no loans or any service i am using from any indian finance organisations.
