ICICI Bank — fake call for redeem points on credit card

Address:

560037

I got a call from this number and said this call is from icici bank to redeem your points. They started saying that my card number and just asked to verify cvv after that i received an otp from icici bank message queue.

That girl over call insisted that we are not faking as this message is from icici bank and they deducted rs 6990 from my card they also said it will be refunded after 72 hours.

I got a message saying: 6, 990 transaction from yourattire.co.in

Question here is how do these people get our card info, mobile number?

Don't you guys have proper security for customers?

Please try to refund this and treat this on priority, even i will be lodging a complaint soon at consumer's forum.

Please let me know if more information is needed.
