The complaint is with Navient. 
Navient refuses to provide the outstanding balance on loans when interest is capitalized or payments are received. Their online service only provides the original loand amount and the current balance. However, when viewing transaction history, the total balance is not shown, only capitalized, charges, and payments. Upon calling to ask for balance amounts before and after payments, all supervisors refused to provide me with this information. I was instructed to take the original loan amount and manually go through the transactions line by line ( from origination date in 2007 to present ). 
The practice of refusing to show a running balance due per transaction hurts consumers, and can esily lead to unscrupulous or abusive practices, as the consumer is essentially 'flying blind ' on the total due per each transaction. 
Upon speaking with Navient, they were unwilling to provide a transaction history with all transactions listed and how the balance has increased or decreased. This should be mandatory to provide this information to consumers upon request. Please investigate the legality of this practice by navient.
