On XXXX/XXXX/2015 an online dispute was initiated by me with Equifax, concerning a collection reporting by XXXX XXXX XXXX an amount of {$6700.00}. The investigation was completed by Equifax on XXXX/XXXX/2015. Only 2 days. This led me to believe that a proper investigation into the facts were not done by a human, and the results of this item remaining on my report were all computer generated. I filed a XXXX dispute via telephone on XXXX/XXXX/2015. I asked the agent if any documents were sent by XXXX XXXX XXXX to counter my arguments and documentation from the XXXX dispute. Her response was " NO ''. The agent also assured me that the collection agency will definitely be required to send documentation the next time. This XXXX investigation was completed on XXXX/XXXX/15, only 1 day. They claimed that the debt was verified, and remained on my credit file. I called Equifax again and requested the documents that were sent by the credit collection agency to disprove my information. The agent, ( who would not give me her last name, or the location of the office she was working out of ) informed me that I was not allowed to know what the collector sent to disprove my information. I then requested to speak to a Supervisor. I was connected to XXXX XXXX from the Equifax office in XXXX GA. XXXX XXXX XXXX told me that I was not allowed to know the information that was sent by Resident XXXX XXXX that supposedly countered my arguments for the incorrect reporting. He also said that his agents are trained not to supply a consumer with their last name or office location. I found this highly disturbing due to the fact that these employees had access to all of my personal information right at their fingertips. I also informed him that no documentation was sent by the collection agency to refute my claims during the XXXX investigation, and therefore the this negative information should have been removed. XXXX XXXX continuously insisted that the debt was verified and reporting correctly.
