AutoNation Honda Dulles

I bought a car recently from Dulles Honda where I ended up paying $ 2000.00 more than what I have been agreed to pay by salesman . Here is what happened: After lengthy negotiations the sales person & I agreed upon the outdoor price that I will pay excluding interest & he lets me sign on it by convincing me that is what I will pay outdoor. Even if I signed that paper the sales person eventually takes me to the other finance office which I would like to call it The Slaughter House where I signed another paper with different price tag i.e. around $2000.00 more than what I have been told to pay by sales person.For that matter I have all the necessary papers . Long story short, please please let me know how I could get back my $$$$$ from the big hand because that money is a lot for someone like me who struggles financially. I really appreciate anyone who would like to share ideas , [contact info removed]
