My son has several school loans under American Education Services. I have to help him make his payments each month. When I go onto their online payment system, I have been paying amounts in increment installments on all loans by using their payment system. I pay each installment by the end of the month. Every month, I have been getting harassing calls by this company who states that my payments are delinquent. There is XXXX payment that they have been carrying over for over 40 days stating that this payment has not been made. I spoke with the supervisor and he claimed that the payment went on another loan. How can you use their payment system and request that this payment be made to this loan and it gets applied under another loan? This is not the first time that this has happened. I feel that I have paid them double the amount on my loans. For example, I paid my loan installments, in full, on XXXX payment in the amount of {$600.00}. The following month, I received a call from AES and they stated that I had a delinquency of {$300.00}! This amount also included late fees. This has happened before and when I approached AES that I wanted a summary detail payment list, they would not provide me one. The supervisor looked into it and stated that my money was allocated to other loans rather than the ones that I had indicated. This has happened to my daughter 's student loan that she has with AES, so this method is practiced quite frequently. American Education Services is the ONLY lender that places harassing phone calls. Other loan companies will call and ask if you have made the payment, and if you tell them that you will be paying the following week, they accept that statement. I do know that there are some people that will not tell the truth, and when they are asked about when they will be submitting payments, they lie. However, for someone like myself, who considers myself as a good person, gets harassed to the point that I have to hang up the phone. This has got to stop, not only for myself, but for other students who are desperately trying to pay back a student loan under this very poor economy. Another question, why do n't they allow students to pay on a monthly installment that they can afford? AES requires that you have at least a $ XXXX job so you can handle their payments. This does n't necessarily happen with students who just get out of college. And with the economy now, it will take a long time before they get to that level of salary.
