While serving in the United States XXXX, I received XXXX to travel from XXXX XXXX, XXXX to XXXX XXXX, XXXX in XXXX of 2010 in order to complete my XXXX requirements to be XXXX from the military. I purchased a ticket with a government credit card ( Citibank ) with the belief that I would be reimbursed, or the finance department of my parent unit would settle the debt. I was unaware, until several years later, that the bill had not been paid. For background, when a soldier processes out of the XXXX, every department must sign off on the XXXX. XXXX of these departments is Finance. A soldier is not ( usually ) allowed to clear the installation and XXXX with any outstanding debt owed due to military service. It was for this reason, that when I visited the finance department to obtain clearance paperwork for my XXXX I was assured that I did not owe the outstanding amount on the credit card, and that it would be settled. I have attempted to reach an agreement with both the card issuer and the debt collection service to which they sold the debt, with no success. I have also attempted to remedy this situation through the military, with no success. 
This is a serious blemish on my credit, and I would like to get it resolved. I have not been reimbursed for this travel expense, as I was unaware that the debt was owed and therefore did not submit a travel report which reflected the amount of the ticket.
