Citibank — Credit card misuse

Address:

560008

Hi all,

I got call from the below number [protected] they told call from citibank and your citibank crdit card reward point has deposit as amount and get the daetails and generated one time password (otp).

I not at all shared one time password even though amount deducted rs14500.
They generated 7 time otp continuously i not shared otp but amount deducted. i dont know what is the use of one time password.

Very concern about security system in citibank.

I checked customer care even though they not give proper response.

Thanks,
Siva
