Got a denial letter for unemployment, what now?, payroll clerk here

My claim was denied after 5 weeks of waiting, and the letter says I have a short window to appeal. This is my first time dealing with any of this. My employer's version of events does not match mine, and I have emails that show it. Should I ask someone for free legal help?

I printed my emails in order and wrote a one-page timeline. The hearing officer kept going back to it.

Thanks for writing this out. I went through something close to it 5 months ago, and it settled down once I kept a simple log of every call and form.
