Auto loan questions

Okay I am having alot of issues with the below Auto Loan account. I have had this account since 2006. I was paying this account fine until I was laid off from work in March of 2007. I was 30 days late in May of 2007, and from then on I didnt pay the note. The car was eventually charged off in September of 2007, but the car was not reposessed until January of 2009. I called numerous times regarding the loan and I was once told the account was sent to their in-house collection agency and it had been sold, and then another time I was told it was actually assigned to the in-house collection agency. Which is even more confusing because how can you sell or assign something to your in-house collections dept. It was never marked on my credit bureas as reposessed. I never recieved a letter of defiency for the remaining balance after the car was auctioned. So I'm not actually even sure what it is that I owe on the car. I recently disputed the account for the balances being incorrect because the original amount of the loan was the amount they claimed was charged off. Well when they updated they updated it as a paid charge off and took the balance down to $0. Whats most confusing is I havent paid them one red cent, but they show the date of last payment as July of 2009. I really dont know how to handle this and I have no clue on whether to let sleeping dogs lie, and just take it as a blessing that it has been updated to paid chargeoff instead of a repo, or if I should send them a request for validation considering that they are blatantly lying about recieving any type of payment from me. Any help on this would be greatly appreciated.
