Reserve Bank Of India [RBI] — my account was debited without any transaction [protected] (sbi)

Address: Sivasagar, Assam, 785640

Dear concern,
My account has been debited 2500 without any transaction done on 17th. I have approached my bank. But they are also not able to tell what is the reason for this debit. They asked me to call the customer care they are asking me 16 digits debit card and pin no. Which i cannot give. The transaction shows as swoo debit. Kindly look into it dear concern. This is a kind of fraud only because without my knowledge amount got debited.
