Employer Lying about termination!! PLEASE HELP

I was fired, I repeat fired from my job. An employee and I had a small disagreement, there were no threats or physical confrontation involved and I asked my boss if I could go home and take vacation hours for the rest of the day to avoid anymore confrontation. My boss said that was fine and when I came back that evening to pick up my pay, he was waiting for me at the front gate, wouldn't let me in to get my things out of my locker, had called the police in the opposite county from which I live to protect the other employee for no reason, and told me he had to let me go. When I went to file my unemployment I recieved notice the the company was saying that my termination was voluntary, which was not the case at all. I never quit. I called the Vice President of Human Resources at my company and she said that my boss had given his statement saying that I entered his office at 6:30 a.m. that morning and said "I quit, I can't do this anymore." I was never in his office, I never said those things, he met me outside of the workplace and gave me my pay and told me that he was letting me go. Law enforcement was also called on me for no reason, I never made any threats or had a physical confrontation with the other employee. There was no reason for my termination. Now they are lying and saying that I said I quit. WTH? What can I do about this?
