Product: Vehicle loan or lease

I am a XXXX year old college XXXX, worked three jobs to pay for a reliable car to get to work and school. I was working late and dealing with the homeless people on the bus and public transportation late at night. My car was repossessed three times after losing two jobs due to my school schedule by Santander Consumer USA, loan company. After the third repossession in XX/XX/XXXX, Santander Consumer USA loan company stated that I could not reinstate the car payments to get my car back ( my family in the past had helped me to get the car back from repossession ). While picking up my car after the first repossession, another person was there at the same time as I was to pick up his car and he stated that Santander Consumer USA had repossessed his car twice in less than two months. Therefore, since Santander Consumer USA stated that after the third repossession, I could not get the car back, the car was scheduled for auction according to Santander Consumer USA. I received a letter from Santander Consumer USA with the amount that I must pay after Santander 's letter stated that the car had been sold and a balance of approx. more than {$19000.00} is due on the XXXX car after the car was sold and which I paid approx. {$21000.00} in XXXX. Santander also mailed a letter stating they would take a settlement of approx. {$5700.00}, if I contact them before XX/XX/XXXX. The letter state that the settlement had possible tax impacts for myself. I need to know what the true balance after the sale of car by obtaining a copy of the Bill of Sale for the car and where did the auction of the car take place information from Santander Consumer USA. After several calls and failed attempts to get information about the auction sell amount and the auction place of the car, I wrote a letter in XX/XX/XXXX and XX/XX/XXXX after not receiving a response to my requests for information about the sell of the car to Santander Consumer USA.
