I had XXXX private student loans with Sallie Mae while I was in school. I refinanced these loans in XX/XX/XXXX with XXXX, XXXX XXXX sent Sallie Mae payments on XX/XX/XXXX and sent me a receipt for payment. Sallie Mae had n't processed the payment on XX/XX/XXXX and wanted me to pay them for a loan that was already paid off. I called and they told me I would have to pay a {$50.00} fee to be put in forbearance so they could research the issue, the issue was their fault from their company splitting in fall XX/XX/XXXX and they should have it resolved in a week or XXXX. I paid the fee and waited and then I received a bill in XXXX telling me I still had a payment due. I called and they had no record of my dispute from XXXX, and told me the only way they would research their mistake is if I electronically sent them proof of payment from XXXX or if I conferenced called them with a XXXX representative. Also, XXXX had overpaid in XXXX so Sallie Mae was actually holding over {$350.00} of my money.
