I contacted Citi on XXXX XXXX at XXXX at XXXX. The representative was unable to locate my account when searching by the account number, numbers at the bottom of a bill, my social security number or my full name. She thought this was very strange and I was very upset. I advised her that I have been paying this bill every month and I am extremely concerned that I pay them {$80.00} per month ( or more ) for an account that they are showing no record of. How can a creditor collect a debt from you that they can not even track in their system?
