They keep calling numerous times a day, shows Citi bank (I have no accounts with Citi bank!). Robo dial and caller ID helps: the phone rings once and that's it. Still, VERY annoying.
Called my 215 area code mobile phone number on 2017-07-12 at 8:58am EDT. I did not answer. Caller did not leave voice mail. CallerID was the phone number, Caller location: Irving, Texas. I am not a Citi customer.
