AES http : //www.aessuccess.org/ is a company that handles my XXXX private student loans : XXXX loan is in my name solely and then the other XXXX are co-signed ( XXXX by my mother and XXXX by my father ). All XXXX of us log in separately to AES website to pay our individual bills. My complaint is against their customer service and their website on how the loan and billing information is displayed and how the payments are distributed. The information is misleading and the balance does not always accurately reflect a true balance. I logged in this month and the system showed me a balance which matched the exact amount that I have paid on the loans solely in my name for the past 10 years only to find out that AES applied that money to the loan my father co-signed on because his was also due. The information their website showed me did not give me any reason or indication that the money I was sending was going to be applied differently. When my father logged in to pay, his amount was less ( because my money paid part of his loan ) and now my account is delinquent. All three of us logged in and at the time of log in, satisfied the payment balance ... but their system is glitched or does n't properly show the information because the full balance was n't paid because their system never accurately showed the information. Money was sent to the wrong place and then because of it, the wrong balance was shown to my father who then paid less than he usually does ( thinking the rate changed or something happened to lower the payment ). It 's confusing. It creates undue stress and anxiety. Their system needs looked at and their customer service investigated. The supervisor, XXXX, also gave me conflicting information and admitted that she read the screen wrong. Which leads me to believe they struggle with getting accurate information out of their own system. Please investigate and help.
