Address:

560016

An employee of citibank who has either quit the company or doing it from within citibank called up with all my credit card confidential information like credit card number, expiry date, cvv and including credit reward points which was only known to me. Believing that it's a legitimate caller from citi i shared the otp and he took out 1 lakh 12 thousand from my cc to top up his paytm and mobiquik. An fir is filed with bangalore cyber police and the investigation is on, citibank is constantly harassing almost on daily basis to make the payment without actually doing the investigation and finding out the fraudulent caller who is sitting out there and doing the same thing with many other customers.
