<human>: Can you give me the gist of the text in a nutshell?

On December 18, 2014 I took my car into the dealership to be serviced.  While I was there they offered me a free appraisal on my vehicle, which I took them up on.  As I was checking out their used car selection a salesman approached me.  I told him I wasn't interested in buying a car, just having mine serviced, but asked for some information on a used car in the lot.  When I came back inside the dealership we talked some numbers and started going over loans and trade in values, but they kept trying to stiff arm me into signing the loan paperwork so I walked away from them.  Now I'm getting letters in the mail from loan agencies saying I've been denied for loans I never applied for, and they're coming almost weekly.  I went from having a low 700 score to a mid 600 in the span of three weeks.  Is there anything I can do to refute these loan applications and return my credit score to what it was?
<bot>: Walked away from signing paperwork at a car dealership because they were pushy, now I keep getting denied loan applications in the mail and my credit score is dropping
