Reserve Bank Of India [RBI] — phishing phone call for credit card info

Address: Chennai, Tamil Nadu, 600119

Hi,
I received one call from [protected] at 28 sep 2018, 1.57 pm
The person introduced himself as sbi representative and said me i am carrying 8000+ reward points against my sbi credit card.
He asked me to redeem points as it will be expiring tomorrow.
He asked my dob, card type, expiry date, and last 8 digit numbers.
Off course i gave everything fake info to reveal more info from home.
He revealed him from chennai t nagar sbi branch, name as vikram sing, sbi emp vs23805 which i suspect is fake.
When i asked him t nagar ifsc code he disconnected the call.
