<human>: I had a little over $11,000 in loans from Sallie Mae when I graduated college in 2009.  I saved up as much as I could and I have been slowing making extra payments and paying down the principal.

At the beginning of this month I realized my normal extra payment would be more than what I owed.  I used the loan payoff calculator on their website to calculate exactly how much I would need to pay in order to completely pay off the principal, current accrued interest, and any interest that would accrue between when I sent in my payment and when it was applied.

I paid the calculated amount, and two days later my account was was paid off and then some, by 42 cents.

Granted, it's only 42 cents, but it's my money and I don't think the accounts can be listed as "paid in full" until the balance is zero.

I emailed Sallie Mae but they said I would have to provide a bank statement showing the payment or wait 30 days and then request a refund.  The bank statement thing makes no since to me since they obviously received the payment because my account is in the negative.

Anyone else ever deal with this?
