Direct Loans review: Student Loan 1

I have been paying on my default student loan each and every month and I thought I only had one or two payments left. My last statement balance showed I only owed 143.68 and I had mailed $50 which had not been reflected in that balance. I recieved a letter stating my loan was no longer in default and was being sent back to Direct Loans. I recieved a letter from Direct Loans saying that my pay off balance was over $5, 000! I called them to tell them this was a mistake and they assured me that it was what they had on record. I then called the default department and had them mail me a copy of all payment history so I could dispute it. I spent over 2 hours on the phone with Direct Loans and the default resoulution company before finally finding a supervisor that could help me. They told me it was a mistake they had never seen before and somehow my loan had been hanging on their file and it looked like I had never had it in the default department. (I'm not really sure what this means but they assured me it would be corrected.

Two months later and they are still saying I owe $1, 035 in interest that has accurred. When I called to find out how this is possible on a loan that should have a balance of less than $100, (which now they are giving me a balance of $184). They can not tell me where this amount is coming from. I have my account history on paper but they are STILL trying to charge me all this interest! I don't know what to do. I can't afford to keep paying. I'm a single mom with 4 kids and I can not afford to pay this! Default is telling me that I have a zero balance but the people at Direct Loans are telling me they are gettig these numbers from default.

I just wasted another 2 hours of my day today and still nothing accomplished. I asked Direct Loans to mail me a copy of all my account info. I'm sick to my stomach after dealing with these rude supervisors :(
