877-689-8870

I ignored the call.

I blocked them after repeated calls. No message was ever left.

Robot said it was for "debt collection"; named specific amounts due, but not what the account was!  Then offered ways to pay; finally said that you could also find out more at www.citycards.com  which turned out to be a German advertising company!

Falsely claim to be Citibank (Scam call) reported by Gary
Robocall that knows your name. Asks you to verify your first and last name by pressing 1. Claims to be an important call regarding your Citibank Costco Anywhere Card. Gives 877-689-8870 as the callback number to speak with someone. Called Citibank directly using the number on the back of my card, they told me that they did not call me. I've aggressively been called several times a day now.Please don`t provide any info related to your account .
