My private student loans are serviced by AES. Over the years I have had significant difficulties with the loan servicer not providing accurate information in regards to my loans. More recently, I attempted to have my parents released as co-signer of my loans only to find out that after a few years earlier being told that I could have them released after a certain period of time, I learn that I was denied co-signer release because the terms of my loans do n't have a co-signer release due to the years they were dispersed. When I question who the owner of my loans are I have n't received an answer. I originally borrowed from XXXX XXXX XXXX and on my credit report as well as my parents credit reports it says NCT. I have been requesting from AES proof of who owns my loans as well as contact information for NCT for nearly 2 months now and I am told that they do n't have information to contact NCT. It took them nearly a month to provide me with my original promissory notes ( finally received them yesterday ) and even after very very careful examination of the fine print of those promissory notes not anywhere in any of the documentation does it state anything in regards to a co-signer release or that the loans are not eligible for co-signer release. I have demanded that AES provide me with documentation of the co-signer benefits and stipulation but have yet to receive much more than a generic almost computer generated response. Even when you call them it seems as though the customer service reps are trained to respond in certain ways and that their knowledge is lacking as well as their customer service skills. I 've seen news stories on how NCT likes to sue people for not paying their loans but then when they get to court they cant prove that they are the owners of the loans.
