Product: Debt collection

I'm an XXXX XXXX military person with a government issued Citibank Travel business card which is used to pay for my military travel. Today, I received a notification that my travel wasn't booked because of an issue with my government issued credit card. 

I contacted Citibank Travel to inquire and they informed me that there was an outstanding balance of roughly {$2.00} that wasn't paid on my last expense report ( a payment of over {$5000.00} was made at one time to cover the entire cost of the trip ). After 4 phones calls today, I was told by a supervisor the international currency fees weren't accounted for when payment was submitted by my military credit card manager which was the reasoning for the {$2.00} fee. I asked for them to provide documentation that they attempted to contact me but no documentation was provided. There response every time I asked that question was that it's my responsibility to ensure the mailing address on file is correct, as it was supposedly showing my previous residence. I informed them that when I moved to my new duty station, that I updated all of my information, to include my credit card information on our travel credit card program and that I wasn't sure why that wasn't reflecting since each time I login to the system, it asks me to ensure my credit card information is correct. I also informed them that my travel claim will not process unless every penny is accounted for, which in every situation, has always resulted in the entire balance being paid in full ( by the military, they pay off the credit card after every travel - not me - I'm as far detached from this as anyone could be ). To make matters worse, they suspended my card for 60 days despite me offering to pay the balance in full on the spot when I called today and said there was no exception to this policy and that regardless of payment, there was nothing that they could do to reactivate my credit card which means my official military travel next week has to be cancelled. 

The new total balance owed is {$140.00} I believe vice {$2.00} and some change because they charged me 2-3 late fees as well as a wage garnishment fee to have the military pay system called XXXX, garnish my wages for the balance. The fact that no mail, no phone calls and no notification from my command makes me question the legitimacy of these fees and whether or not the company actually adhered to their own policies. 

When I spoke to the supervisor I asked the following " why would I pay ( the military ) over {$5000.00} in a single payment and not pay the other {$2.00}, and why would you think that I purposely avoided paying the {$2.00} ''. I then stated to them if I was going to be delinquent on paying them, it would be for {$2.00} and to use some common sense that this was an oversight on my military travel office. 

At the end of the day they didn't care, they wanted their {$130.00} in fees that they assessed I owed and could care less to use common sense or attempt to have a real person call me to inquire about the delinquent payment and instead just sent it to the collection agency to have my wages garnished. I'm XXXX years old, am still serving on XXXX XXXX for the last 24 years and have a credit score of 800-815. Their attitude, behavior and demeanor was the most rude and hostile phone call I've ever experienced in my entire adult life. 

Anything you can do to assist in this matter is appreciated and I thank you for your time.
