On XXXX XXXX attempted a payment for private loans with Navient account # XXXX. My online account showed a fee of {$14.00}. My account was current due to IBR and on-payments. My total amount due according to the system was to be {$530.00} with their Quick Pay system. My card was charged {$14.00} and {$330.00}. The rest of the payment was unprocessed without confirmation. I contacted customer service and Agent # XXXX confirmed that {$14.00} was a for a late fee which was to be applied to interest on my federal loan. My federal loan is on a $ XXXX and the rep said I did not owe this, yet I have been charged. I called again today and logged into their system and the account is showing that {$480.00} is owed. Which is incorrect. The system declared an amount owed for XXXX XXXX loan was {$150.00}, Agent XXXX 's system said {$140.00} was owed and processed that amount. Why is Navient continually showing late fees that are n't on a borrower 's account with an autopay system that just collects this. Even when I have tried to keep my payments current the system is overcharging and so is Navient. This system is designed to keep people in debt! This is outrageous! My student loans combined are more than XXXX of my income. I can barely make ends meet! Also it seems the only way I can get them to do anything right is via phone with payment by credit card and now they are charging {$15.00} to process this way and this is the first time they have disclosed that fee. When they overdrew my account before at no time was there every acknowledgement of any fees charged! Why is my statement showing more than what I owe? Are they arbitrarily adding money to my loans? My balance is $ 107+! Please advise.
