Product: Student loan

I have student loan accounts with Navient and am also the co-signer on two of my daughter 's student loan accounts. I recently received notification that I was delinquent on my student loan account. I usually pay {$110.00} per month ( which is beyond my minimum monthly payment ) and believed this was a big error. I began searching through my previous payment history and found Navient has been misapplying my payments. They have been taking my personal payments and applying them to my daughter 's accounts, which is unacceptable. This has happened 34 different times since XX/XX/XXXX but the majority of misapplied payments have been occurring since XX/XX/XXXX. The total amount of misapplied payments is  {$3300.00} which should have been applied to my personal accounts but instead applied to my daughters. The remaining amounts that were applied to my account only went towards interest - nothing was applied to my principle balance which means my balance has not decreased in a very long time. In some situations, they didn't apply the payment to my account at all which resulted in a late fee and negative credit reporting. To ensure I did everything correctly when sending in my payments, I checked the company 's website and found disclosure on how/where to send payments. These disclosures have two pieces, one for the primary borrower and where to send the payments, and one for the cosigner and where to send the payments. I have been sending all of my payments to the primary borrower payment location as their disclosures state so there is no reason for the company to take my money and apply it to my daughter 's accounts. When I tried to call and talk to the company, their customer service representative was very rude and told me I had to " prove '' my case. Here is all the proof they need. The company 's unfair and deceptive payment allocation practices have not only caused improper handling of my account ( which should be paid off by now due to the amount of overpayments I have made ) but have also incorrectly charged late fees and incorrectly reported me to the Credit Reporting Agencies. 

In the attached documents, you will find enough evidence to prove their wrong doing. One is my payment history I retrieved from the company 's website. The highlighted portions show late charges, my payments being applied to my daughter 's account ( her accounts are the ones with the name " XXXX '' ),  along with proof that no principle has been paid on my account. There is one payment from XX/XX/XXXX that was made to my daughter 's account - she had just entered college and was still having active disbursements. This payment was misapplied to her account. In addition, you will find the last two years of payments to the company that my personal bank supplied me as evidence to show I truly made these payments. Lastly, I am providing the company 's payment disclosures I referred to earlier. 

I am asking for Navient to reverse and reapply all of the payments I identified within the Navient History document to correctly apply them to my account only. I also want the late fees waived and my credit reporting fixed. Lastly, I expect a refund of the overpayment, to include interest, because if they would have been applied correctly the first time, my account would be paid off by now. Lastly, I would like a transaction history reflecting all adjustments made for the life of my loan to ensure this was executed properly.
