State Bank Of India [SBI] — sharing customer data to frauds and credit card fraud.

Address:

560079

I got a call from some unknown person stating that she is calling from sbi bank and told all my card details including card number, expiry date, home and office address and cheated me 20000rs by taking the amount to some payzapp wallet and even payzapp customer care number is not working and even they are also fraud. How did sbi shared my my data publicly and what is the security for the people using sbi cards.
