In XXXX 2015, we made a {$12.00} payment to our Citibank credit card account, which was the full balance. For reasons that have never been adequately explained to us, this payment was returned to our account at XXXX XXXX by Citibank. Citibank then charged us a {$35.00} late fee after rejecting the payment for the principal. We sent the payment for the {$12.00} principal, and called Citibank, requesting that they waive the late fee. They refused to waive the late fee, for reasons they would not explain. We requested that the account be closed, and were told that this would be done. 

About two weeks later, we were contacted by Citibank again, requesting payment. At this post, they had charged a XXXX {$35.00} late fee, apparently related to the XXXX late fee, as we had already paid the principal. They also told us that the account had not been closed, despite our prior request. 

Tonight, after speaking to XXXX different representatives at Citibank, we were told have an approximately {$82.00} balance with them, reflecting their fees upon fees for an initial {$12.00} charge. They confirmed that they had returned our payment, but could not explain why it was returned. They could not explain why our prior request to have the late fee waived was denied, and they could not explain why our request to close the account was not acted upon. They stated that they will have a manager investigate this further. 

The highest level contact I have made to date was with XXXX, ID # XXXX. We have made about XXXX calls to date to Citibank to address this, and we have no resolution at this point.
