[Resolved]  ICICI Bank — Credit card verification process

Address:	Mumbai City, Maharashtra

Hi ICICI Bank Authorities
I have an ICICI credit card that expired last month. I was given a replacement from the bank, how ever had not activated it yet. I received a call from a cell phone number which stated that they are calling from the Mumbai Credit Card Verification department and that they wanted to transfer my reward point from my old card to the new card. For this they asked me my DOB, expiry dates for both cards and finally the 16 digit number for the new card.
When i refused, they passed the call over to 4 other people who sounded like normal customer care personnel and all of them tried convincing me to divulge my card number over the phone.
I asked them for an alternate method of verification and even gave the option of going to the bank and confirming. They kept on insisting for the 16 digit number in my voice.
I was very suspicious of the whole process and refused to share details.
So finally after a heated conversation i terminated the call.
Kindly let me know if this is a standard proceedure at your end. If so, there should be better ways of doing the same without raising suspicion and having to force a customer to give out details he doesnt want to divulge.
Hoping for a prompt response from you based on which I decide how to take up this matter.
Thanks
SSK
