I used XXXX to view my credit reports, through them I disputed an account for an auto loan that was 'written/charged off ', bad debt in XXXX, of the 3 credit reporting agency accounts that still considered the account open at the time, I was able to dispute 2 of  them through XXXX . There were no issues with 2 agencies they closed the account with a XXXX balance due to my understanding. The 3rd agency was not listed so I had to dispute directly through ( Experian ) them. The account also showed 'written/charged off ' bad debt in XXXX, there was no negative activity on the account since XXXX of XXXX. The dispute came back that the status would not change XXXX the lender apparently provided proof although none is available to be seen anywhere on XXXX or Experian ) the account will stay as is with a negative, balance owed {$7700.00}. Since the dispute they are now recording FP 's ( Failure to pay ) on the credit report while the other two agencies are not. The name of the credit union at the time I received the loan was XXXX XXXX, they became XXXX XXXX sometime after the purchase. The amount negative shows, {$7700.00}, dispute was completed in XXXX, updated on XX/XX/XXXX, I attempted to re-file the dispute however I was unable to provide more information on the website so I contacted the agency to dispute the lenders contention via phone. It was re-disputed on XX/XX/XXXX and not without difficulty with that, as the agent was basically trying to dissuade me from filing the dispute a second time, I had to ask him point blank 'Are you refusing to file my dispute or what '?. I was told previously to contact the lender directly and I did, I was met with nothing but brick walls. The gentleman I spoke to was either unwilling or unable to assist me and gave me a debt collectors number. I contacted them, yet another brick wall even worse, I felt almost abused by the representative who was raising her voice to me, cutting me off, I almost felt belittled and I requested to speak to a supervisor who was even less helpful. I received absolutely zero assistance from anyone. I then tried to prove my contention that there are 5 factors involved that should be pertinent to my belief the account should be closed without showing a negative balance however since no one will assist me, I'm having trouble proving my point. Point # 1 What proof did the lender show the credit reporting agency that the account should remain open or even closed but with a negative balance? The reporting agency doesn't have anything to provide me showing the proof. # 2, if the lender or debt collector closed the other accounts through the other 2 reporting agencies why did they not close this one without a negative balance? # 3 it is my understanding that a lender is able to write/charge off an account as a bad debt however if they want to claim that as a loss on the company taxes it must be done the year it was written off, that is the only time it can be written off ( again, for tax purposes only ). I can not prove that they did or did not claim it on their taxes, yet they are unwilling to provide me proof that they didn't # 4 I chased down the VIN number of the vehicle, however without spending money to find out the status of the vehicle ( I'm guessing it was resold as it was a brand new car with no issues other then it was 6 months old when I turned it in to the lender ) it is my belief that the car had been resold to potentially recapture the bad debt ( and not only from a tax loss purpose, I'm sure that's a violation of a tax code through the IRS ) so they recouped the money off the resale of the vehicle. # 5 knowing they recouped either the entire amount either through a combination of both ( tax write off and re-sale of the vehicle ) or actually making a profit off they are attempting to increase their profit even further by attempting to collect the debt from me. Is there such a thing as Triple Jeopardy? I  understand that a lender can write/off an account and still state the balance is still due, however can a lender not only recover their loss but gain financially from a bad debt? No one has shown me even a single inkling of proof that the points I provided are not true and accurate. If they have nothing to hide why won't they disclose the truth? If I have to I will subpoena their ( XXXX XXXX ) records but I would hope it doesn't come to that. It is an abuse of the lender and the debt collector towards me by not providing any proof not to mention borderline harassment and oppression.
