Product: Vehicle loan or lease

The vehicle was repossessed after XXXX months of nonpayment without my knowledge, and the finance company only called me to let me know. They repossess my vehicle without giving me a chance to make any kind of payment to them to keep the vehicle, because I was letting them know that there were engine issues that were in the car and they stated that theyre unable to fix it because it was my fault, but I kept letting them know at the dealership and the finance company what was going on with the car issues and I was putting in my own money into it, so it caused me to fall behind on my car payments and they still refused to work on the car and when I said that I would file for a lemon law, they ended up repossessing my vehicle so I wouldnt have proof of the vehicle being their fault, even though it was under warranty. They only contact me to let me know that they took my vehicle and that it is not stolen. However, I requested the deficiency balance after it was sold and I didnt receive anything at all in XX/XX/XXXX. I sent over a certified letter to their office because they stated that theyre on able to give out emails or other information of the company besides the phone number which they kept transferring me to another person, avoiding the question I was asking about the documents for that vehicle. I also requested a copy of the contract, and they refuse to send it, and I have made numerous phone calls and attempts throughout the years to get this resolved, and most recently I made a dispute with the credit bureaus, and they are stating that the balance remains on my credit that is accurate on the lenders end, but I do not agree, because ever since I started disputing it, because it is indeed an accurate. They have been increasing the balance on the loan to a whopping over {$9000.00} when originally it was about {$7000.00} and I do have a screenshot of that as well. And that was the loan amount for when I had a vehicle in my possession so there was no deficiency balance applied, and they just kept increasing the amount and its unfair that the credit bureaus are allowing this on their end because I even called the auto loan company recently in XXXX and they kept saying that the XXXX was on vacation just like they did back in XXXX so Ive been dealing with this issue for a very long time and I need them to get audited or whatever needs to be done and remove from my credit because this has been causing me issues for years and I have not been able to get any loans and has been a major issue for me and my family. I am going to the military and enlisting an XXXX XXXX and I would love for you guys to please help me with this matter because this auto loan company has been giving me the runaround and not following the law and filing a complaint with you is the next step for me before I take it any higher. Feel free to call me at XXXX and my email is XXXX. I have gave the finance company everything I could possibly can give and try to resolve it with them and they still are avoiding me in general because they know what theyre doing is wrong. I can provide the letter that I sent to them and I would love for you guys to provide any documents they sent to you because I have no knowledge of anything thats going on or why they are able to increase the loan balance that is so inaccurate, and very abusive.
