Beware of Scam Calls From (816) 420-4632 or (866) 680-8628
I post this not because the odds are high any of you readers have had this issue but I want these numbers to be found on an internet search.
Both numbers were leaving a message saying they were from "Citi" or "Citicard" calling about my account (and that it was not a sales call). Since I have no Citicorp credit cards or accounts of any type, and since they were calling a Google Voice number that I would never have put on an account (in fact don't even really use), I was totally suspicious. When I called them they asked for my account number. I said I did not have one but was calling to see what kind of scam they were running. They said they were from Citicard and don't do scams, but could I give them my phone number. I said I had to look it up, because they were calling a Google voice number I never use. The moment I said that, they hung up on me, the universal indicator of a scamster giving up.
Update: There is a legitimate Citi group with the same name. It sounds to me that these folks at the numbers above are recording the legitimate Citi greeting replaying it on their lines. But then their physical operator answers the phone completely differently than does the legitimate Citi operator. The Citi group being spoofed is this one.
