I attempted to pay off my student loan with Sallie Mae. During this process I used the system to view the current balance/payoff amount of my loan and checked that option on the payment form. I specifically chose this option and not Last Statement Balance since the statement balance may have possibly been not current. After submitting the proper amount for the current balance/payoff amount the institution billed me for additional expenses. There was no disclaimer or information shared with me that they would process any additional charges and since I selected to pay off the loan it, to my knowledge, payed off the full loan.
