Lithia Chrysler Dodge Jeep Ram of Billings

I stopped in with a mail in offer. A traveling salesman named David told me that I could bid an offer $20,000 below asking and it may be accepted. I asked if I could back out if it was accepted and was told I could. I was asked how much I could pay each month and how much I had for a down payment. Also, I was asked what type of vehicle I desired. After David wrote everything I said down on scratch paper, he asked me to initial my answers. He then told me my offer was accepted and I had bought the truck. I asked if I could back out and he said no you signed and bought a truck. After I discussed this with my wife who is a us citizen, she knew I was deceived and helped me complain. We met with Austin, the gm and Nate, sales manager. They also brought in the finance lady. I explained my situation and my wife explained that I am not a us citizen and have a language barrier as I am a spanish speaker. My English is fair, however I have trouble retaining information. The GM said that is "crap" and would not help us out of this deal. The worst part, I am in 55,925 on a 34,000 truck. BUYER BEWARE
