Received a phishing call today from this number.  Male caller stated that his organization intended to place a $350 "refund" into a Citibank account.  He stated that I would be asked four security questions, but first had to verify my account number. I asked him if I could place him on hold to verify "things."  He agreed.  I left him on hold/mute so he would have less time to commit fraud.  He eventually hung up.

calls frequently, leaves no message

Caller used the name Bank One, which no longer is called by this name, looking for information re funds in this bank. When I told him Bank One is no longer a valid name, he angrily told me he was sorry I didn't get my d--- this morning.
