American Education Services has a ridiculous interest rate type & percentage that changes monthly, making it nearly impossible to pay off a student loan in a lifetime. When I call, employees are rude, and are n't able to describe how my interest rate works, and is calculated, or how/why payments were applied as they were. With the repayment plan they have me in now, I will be paying over {$30000.00} for a less than {$10000.00} loan and will be paying until at least XX/XX/XXXX, for a loan that was taken out in XX/XX/XXXX. In the past 9 months I made extra payments in some months to try to get the principle to drop. In the past 9 months of the over {$2400.00} I have paid only {$1600.00} has gone came off the principal.
