Citi Bank — Getting Fake calls mentioning that I have been issued citibank credit card

Address:

Hyderabad, Andhra Pradesh

Hi, This is Gyanendra Yadav, I have got few calls in last 1-2 month mentioning that I have been issued one citi bank credit card. Initially, I ignored the calls assuming there is some mistake but Today ( Dated 18th July 2015 ) Caller who was a lady, mentioned My name, My mobile no along with last four digit of Credit card no ( which I couldn't listen exactly and he/she dropped the call when asked to repeat). Caller was asking how I would like to redeem my credit card points which has reached to 5000 points. caller used this no: +91- [protected] to call me. This incident has increased my worries to many fold, I never applied, nor using any citi bank credit card. Please look into it or let me know I need to lodge the complaint with TRI or RBI. Thanks & Regards, Gyanendra
