Affiliated Finance Corporation Pay More Money for Nothing Sunrise Florida

To start this off this company finance a 7 passenger Van for me. I was on time with my payments and yes I received phones calls when I was late which is normal for any company. I use to drive to Sunrise and take my payments to them. Can not count the times but I did that offened. I had the vehicle for almost three years and my payments realable. But it seem as thought my payments was not going down each time that I paid on my van. The Van was only $7999 and I had it for a long time. So I got into a finanical bind till were I was not able to take care of payments my husband was incarsarate and I became a single mom. I called the company and told them to come and picked the van up. It took them more than two months to do that. When they did I told them to make sure they send me a paper to sign that I voluntary returned the van. Yes I received the paper work and had him to sign it and I have my copy as of today. So I did not hear from them over two years after that.Than I received a Paper from County Court House that they had been trying to reach me after two years that I owed them $8223.41 dollars and I did not believe what I received after two years. I had moved two times within those two years. They left one paper at my sons address which I did not live there anymore and it was left in his door that he did not sign for. But I still did not receive any paper work as to appear in court for any of this. So after two years and no contact from them and receiving Court papers after the court day. I tried calling those people leaving messages and no one will contact me. My thing is they are charging me the same price as when I purchase the Van. I also looked up the Vin number on the van and located that the van was sold twice after I returned it. As to today that Van sold to the second person in Puerto Rico. Why I am in the County Court House showing a judgement of $8223.41 for a Van that I do not have and been sold to other people. They are ripping me off. I am still calling leaving messages for someone to contact me to remove this off of my credit report. I could see if I owed less than $3000 that do sound right but they took me back to the beginning price. How do I get rid of this from out of the Courts? I need help in this matter.
Thanks
