Due to Sallie Mae’s practices

I was divorced from my wife while on active duty in the U.S. Army in 2008. She was able to obtain fraudulently via power of attorney multiple loans for college that she never attended, and used the money for personal purchases. I found out this information after returning from Afghanistan in 2007, and informed Sallie Mae of this then. During the divorce, the courts stated that all debts incurred by her were her responsibility, and I was not liable for her debts. Due to Sallie Mae’s practices, I am unable to get a loan since my ex wife makes it a point to default on her loan every 6 months to keep my credit score low. I am a retired active duty Soldier, and currently employed by the U.S. Army as a Department of Defense Civilian with a Top Secret access classification. It is my understanding that this debt which now is more than when she first opened the accounts due to her insistence on paying the absolute minimum is hindering my further promotion potential in the Department of Defense for debt to income ratio.
