State Bank Of India [SBI] — unauthorised credit card charges debited from my sbi savings account no. [protected]

Address:

Kolkata, West Bengal, 700030

I do not possess any sbi credit card, inspite of that sbi, dumdum road branch, kolkata debited rs 588.82 from my account [protected] on its own though i have not registered any autopay facility in favour of sbi credit card. I went to branch (Code no. 12373) to lodge complaint, but the officials refused to talk in this matter and advised me to talk with some other officials meant for sbi credit card who sit separately in a table in the branch. I do not know how get back the amount, how to close autopay facility, how to block the card if any issued as i do not the credit card number. Please help me.
