I purchased a XXXX XXXX XXXX XXXX XXXX XXXX in XX/XX/XXXX. I noticed om the contract that too manypayments were listed on the contract. I contacted the dealership and told them and they told me to bring the car back to sign a new contract. When I arrived they told me that my {$600.00} down payment was not enough and that I had to put down an additional {$600.00} and that I needed to sign additional documents. I refused and gave them the vehicle back. 
The car was not reporting on my credit at that time. 
2 weeks later, I received an alert displaying a new account from XXXX XXXX with a {$12000.00} debt. 
My down payment was not returned by the dealership although I returned the car within 5 days. 
Now this new auto loan is displaying on my credit report which is preventing me from obtaining an auto loan as well as a loan for a home. 

I have sent a cease and desist letter to the dealership ( which has been ignored ) as well as contacted the Illinois Stated Attorney. 
I have disputed this account with all 3 credit bureaus and this account still has not been removed.

I am at my wits end!!! 
Please help
