Product: Student loan

I have 2 issues with my student loans. 

XXXX. After loan XXXX sold to XXXX XXXX created a commercial loan XXXX connected to XXXX which is an error. 
A mystery loan account number XXXX for {$1500.00} showed up on my student loan account with XXXX on XX/XX/XXXX after all my student loans with them were packaged and sold to XXXX prior. I called XXXX XX/XX/XXXX and XX/XX/XXXX and reported it. They told me the " J '' at the beginning of the loan indicate this was a commercial student loan taken out in XX/XX/XXXX while I attended XXXX XXXX and did not show up in their system until XX/XX/XXXX. There was another loan account XXXX ( " XXXX '' designation not commercial loan ) showing currently showing a {$0.00} balance as sold to XXXX with all my other loans. This original loan amount and disbursement dates are identical to XXXX. Also, on StudentAid.gov, when I click loan XXXX ( not a commercial loan ) it opens up loan XXXX and shows my payments. This exact loan for {$1500.00} was listed twice in my list of loans and although I have been paying on this loan for years the balance is now {$1600.00} as of XX/XX/XXXX. 
I explained to XXXX that this is not my loan. I did not borrow a commercial student loan. I did not authorize, nor receive any proceeds from the purported commercial loan listed under my name. I believe this was erroneously billed to me due to administrative errors or mismanagement by XXXX or XXXX XXXX. 
After 1 year of requesting the form to dispute the loan so they can correct their error, they sent me a fraud packet that was requesting that I state the loan was identity theft, but I did not I was clear in my report that it was a clerical error or fraud from XXXX and they need to fix it. ( paperwork attached ). XXXX tried to convince me that the XXXX and XXXX are not connected although they were clearly linked online and the XXXX shows {$0.00} because it was sold to XXXX. 
To confirm their own confusion to my dispute, they response letter refer to the loan number as XXXX and stated that my request was denied because " Denied For Borrower Acknowledgement ''. I have been working on this with XXXX for years and and they are aggressively requesting payment and to stop them from ruining my credit I have been paying them monthly until they fix the error. ( letter attached ). 

XXXX. My principal loan is as of today is listed at {$71000.00} and interest is {$9600.00}. 
There are overall massive errors and duplications in my portfolio of loans sold to XXXX by XXXX. Federal guidelines did not allow borrowing over $ XXXX or $ XXXX. However the loans sold to AidVantage showed over {$84000.00} ( included a XXXX loan that is now PAID IN FULL ) and growing rapidly which is XXXX DEPT OF ED rules over 512.522 % of Student Pell Lifetime Eligibility. I believe they erroneously duplicated the original loans and interest or the colleges reported some of these loans twice since I attended XXXX colleges. I did my XXXX XXXX with XXXX XXXX back in XXXX then moved on to Florida XXXXXXXX XXXX to pursue my XXXX degree XXXX - XXXX. At XXXX I was getting close to the student loan cap for XXXX so I had to leave and decided to return to XXXX XXXX to finish my degree because their credits were much less expensive. I did only XXXX semester when I returned to XXXX XXXX in XXXX XXXX and when I left I was still under the cap by {$2000.00} or more so I could still take more classes there. I did not hit the maximum loans of between {$52000.00} to {$57000.00}. 
Somehow in XXXX when XXXX XXXX reported the loans they duplicated the loans I took during my attendance XXXX along with the semester in XXXX while XXXX reported XXXX XXXX XXXX XXXX it as part of their loans also. Or XXXX who does not care made a huge error when and duplicated everything when packaging and selling the loans to XXXX. 
It is impossible for my principal loan amount as of XX/XX/XXXX to be {$71000.00} and interest {$9600.00}. This is either blatant fraud, huge mismanagement to the extent of gross negligence. I did not authorize or receive benefits from the additional unexplained principal loan amount approx {$21000.00} or the accrued associated overstated interest of {$9600.00}. I contacted XXXX  XXXX XXXX XXXXXXXX XXXX, Student Aid.gov., made a complaint to Ombudsman on Student Aid.gov and AidVantage. While they acknowledge the obvious abnormality, no one wants to fix this error as it is not in their financial interest to fix it. XXXX sold an overstated loan to XXXX, while it is compounding interest at an alarming rate and am paying on these loans monthly and no one will fix it. My complaint to studentaid.gov is now deleted as if it never happened. XXXX no longer pick up the phone when I call, and Department of Education does not answer my calls. This duplication error is approximately {$21000.00} and none of the institutions wants to take the responsibility and fix it. They keep charging me interest.
