Got a denial letter for unemployment, what now? - any advice?

I got a denial letter last week saying I left my job voluntarily, but I was let go as a warehouse supervisor. It has been a long 24 weeks. My employer's version of events does not match mine, and I have emails that show it. Did you bring documents or only talk?

Thanks for writing this out. I went through something close to it 7 months ago, and it got easier once I kept a simple log of every call and form.

Legal aid offices and some workforce centres help with unemployment hearings at no cost. A call is worth it.
