Denied unemployment, how do I appeal? - 12 months and counting

I got a denial letter last week saying I left my job voluntarily, but I was let go as a pharmacy technician. I worked as a pharmacy technician before this. My employer's version of events does not match mine, and I have emails that show it.

Thanks for writing this out. I went through something close to it 12 months ago, and it settled down once I kept a simple log of every call and form.
