She intimated me that due to previous all transactions with my card i have offered a reward of rs 5000. After that she informed me about all my transaction which i did with my all card details and as a proof she told my full address which is enclosed with bank and even she told my correct date of birth also. I don't know how is it possible. Then she guided me to type my cvv no through my cell phone. After some time i received a otp and she forced me to say that. When i ignored that she told that she is genuine from sbi credit card and not to worry, if i have any doubt i can enquired. When i asked about my last transaction she replied as correct. Then i said her the otp which was needed for her. A msg shown on my mobile screen which was rs 9, 999.00 was spent on your sbi card ending 0866 at paytm payments bank on 21/08/2018. Available credit limit rs 19.68. When i informed her about the same she replied don't worry sir it will come including your reward point rs 5000 total 15000 by tomorrow and she cut off the line.
