I previously filed the following claim : Case number : XXXX. At the conclusion of the claim, I received the attached letter from XXXX. The letter states my payment terms are for 24 months. The repayment plan began in XXXX of 2015. 
On XXXX XXXX, 2015, I received the attached letter from Great Lakes. The Great lakes letter has my monthly payment increasing, after just a few months of payments, over 240 %. With the next payment being due XXXX XXXX, 2015. 
If I call Great Lakes I am told to call XXXX. If I call XXXX I am told to call Great Lakes. 
I just received a job offer and I have to borrow money to relocate. Plus, missing a payment could damage my credit enough to cause me to lose the job offer. 

What is happening is not right. Please investigate for me. 

Thank You, XXXX
