Back in September 2005, I wrote Actually, No. about Citibank’s self-defeating fraud department, and the follow-up two months later Reply from Citibank which was just a form letter noting that they had received my complaint.
In that situation, their fraud department would call from an unverifiable number, potentially leaving a voicemail for you, asking you to call them back at an arbitrary unverifiable phone number, where they immediately ask for your account details to verify a transaction. As far as I know they still continue that asinine behavior.
Today, I got a new one: Citibank called to verify a transaction (presumably a large-ish payment I made to a new payee using online bill pay), and the caller asked me to verify receipt of an SMS message (“for security reasons”) by reading him the numeric code it contains, in order to verify they are in fact speaking to me. I told him that I received the message, but I was not comfortable giving him the code, as I could not verify who he is. I explained that he could just as easily be trying to e.g. gain control of my account and needing the verification code to complete a password reset or similar (social engineering me). I told him I would call the number printed on the back of my card, and asked him how to get back to him when doing so. He said he would leave a note on my account.
Of course, when I called back and authenticated to the agent, the agent tried to internally transfer me to the number left in the note (the fraud department), but instead got a message saying the department was closed (open only until 6pm Eastern time) despite someone from that department calling me literally 1 minute prior. It took the customer service agent tracking down the specific employee who left the note, and messaging him, to get me transferred to his personal extension, since going through the department extension wouldn’t work. In the end, it was in fact Citibank’s fraud department calling me, we verified the transaction they wanted to verify, and everything is cool on that end.
However, the bigger issue is that Citibank’s “fraud department” procedures are asinine and extremely self-defeating. I guess it’s time for another complaint to the executive office, and probably another form-letter reply.
