I co sign a private loan with Wells Fargo, I have paid over XXXX, XXXX towards the private student loan. Out of all the money i have paid I still owe more that what the initial loan was for. The loan was for XXXX and I owe XXXX. I have paid over XXXX. The loan was taking out XX/XX/XXXX. I started repayment XX/XX/XXXX. This is unfair to how much interest I 'm paying and nothing is being applied to the principle balance. They will not allow me to lower the interest rate after several attempts.
