AES is servicing debt from a XXXX but I never signed anything from XXXX, I have no proof that they still own the debt which is required. I have asked for proof but AES claims they only service the loans but they should have that information before they collect any money from someone. I need proof that AES is suppose to collect on this loan and all negative credit marks should be removed by law since no one ever inform me that XXXX purchased this debt. I talked with the credit bureaus and they told me that AES must have this information in order to collect on this loan. I never received and I have recorded calls to prove it. I also recorded other calls and they did not give the mini Miranda on the last XXXX calls with them which I have recorded as proof because I do not trust AES, they are criminals and should be arrested. AES often gives out bad information, their automated system gives out the wrong amount which I have recorded and the supervisor on XXXX/XXXX/15 acknowledged the system was incorrect but they never fixed it. This is illegal per federal law therefore all credit marks should be removed. I need all of the credit marks removed so I can get the loans consolidated with a new company that I trust. XXXX XXXX keeps claiming that I am lying even though I have the recorded calls to prove it. The reps clearly do n't know what they are talking about, XXXX told me they did not have to send me proof that XXXX owns this debt even though they send letter saying I owe every month.
